The Inverse Method of Calculating ArraysThe programming principle of the determinan-keyboard reversal method was as follows:
First of all, the value of the button was obtained by assigning values to the port of the single-chip computer twice. For example, take the low four bits of the single-chip processor port (such as the P1 port) as the row line and the high four bits as the column line.
1. The first time you assign a value of 0x0f (00001111) to the port, if a key (such as the 0 key) is pressed, the actual value of the port will change (such as 00001110).
2. Then, he assigned the port a value of 0xf0 (11110000). If the 0 key was pressed, the actual value of the port would become 11100000.
3. By adding the actual values of the two ports (such as 11101110, or 0xee), you get the corresponding value when you press the 0 key. By analogy, the corresponding values of other keys could be obtained, and this corresponding relationship could be established to solve the algorithm problem in matrix keyboard programming.
In programming, the following operations were generally required:
1. define variables, such as variables that represent key values and variables used for loop counting and other purposes.
2. The key detection operation was performed, assigning a value to the port and detecting whether the port value changed to determine whether a key was pressed. For example, after assigning an initial value of 0x0f to the port, it would detect whether the values of the lower four bits have changed (if there is a key press, the values of the lower four bits will change). If there is a change, there may be a key press, and then an appropriate delay (used for anti-shake processing) would be performed. Then, it would be detected again to confirm that there is a key press and obtain the values of the lower four bits. Then, it would assign a value of 0xf0 to the port and detect whether the values of the upper four bits have changed. If there is a change, it would be delayed and tested again to confirm and obtain the values of the upper four bits.
3. By looking up the table (the corresponding table of key values established in advance) to obtain the corresponding values of the keys or the contents to be displayed, and then perform the corresponding operations, such as displaying the corresponding key values on the digital tube.
It should be noted that the specific programming should be adjusted according to the type of single-chip processor used and the grammar rules of the programming language. At the same time, programming was only for research and learning purposes. It was strictly prohibited for commercial purposes.

For example, if a character was described as wearing shabby but clean clothes, it might imply that he had self-esteem despite his hardship.
- ** Language Description **: Through the dialogue and monologue of the character, the character's personality and psychology will be revealed. The topic might be "What is the significance of a certain dialogue between the characters in the story to promote the development of the plot" or "Analyzing the character's personality from the character's language description". For example, Kong Yiji's "stealing books can't be considered stealing" language in Kong Yiji reflected his self-deception and pedantic character.
- ** Action Description **: Description of a character's actions. For example,"analyze the contribution of a certain action description of the protagonist in the text to shaping the character's image." If a person kept rubbing his hands when he was nervous, it could express his uneasiness.

** 2. Description of the environment **
1. ** Natural environment description **
- ** Description angle and technique **:
- ** Techniques **: association of activity and inertia (For example, describing the forest at night, the quiet is the trunk, the moving is the rustling of the leaves, and the stillness of the forest is highlighted by the movement), the combination of reality and reality (For example, describe a garden in memory, write the layout of the garden, write the fragrance of flowers in memory, and enhance the artistic conception)(The front side described the dense forest, and the side described the difficulty of animals in passing through it), the details (describing the dew on the leaves in the morning, etc.), the fine brush and the white brush (the white brush was like "the desert smoke is straight, the long river is round," using simple language to outline the desert scene; the fine brush would carefully describe the various types of flowers and colors in a garden), etc. The related topic might be "Analysis of the combination of movement and stillness in the description of a certain natural environment and its effects".
- ** Rhetoric angle **: Use metaphor, personification, exaggeration and other rhetorical methods to describe. For example,"analyze the effect of figurative rhetoric in the description of the natural environment."
- ** Scenery angle **:
- [Perception angle: describe the scenery in detail from the perspective of sight, hearing, taste, smell, etc.(shape, sound, color, taste, etc.)] The title might be "Analyzing the uniqueness of the description of the garden from the perspective of smell".
- ** Observation angle **: fixed-point observation, moving steps to change scenery, looking down, looking up, etc. For example,"The article uses the technique of moving steps to change the scenery when describing the mountain peak. Please analyze its benefits."
- ** Scenery order **: From far to near (or from near to far), from high to low (or from low to high). For example,"analyze the effect of the sequence of scenes from far to near in a paragraph describing a village on creating an atmosphere."
- ** Function **: Common topics include "Analyzing the effect of a certain natural environment description on the development of the plot"(For example, the description of the environment before the arrival of the storm may indicate the turning point of the plot),"What effect does a certain natural environment description have on the mood of the character"(For example, the gloomy weather sets off the depressed mood of the character), etc.
2. ** Description of social environment **
- ** Description Technique **:
- ** Combination of Point and Plane **:"Plane" refers to the entire scene, and "Point" refers to individual scenes in the scene. For example, when describing a market, the overall description of the bustling market was "noodles", and the description of a small stall's busyness was "dots". The related topic might be "Analysis of the advantages of using a point-to-point combination method to describe the market".
- ** Simple sketch (plain drawing) and fine drawing **: Simple sketch uses concise language to describe, while fine drawing uses fine ink. For example,"analyze the effect of the simple outline of the ancient tavern in the article on the social style of the time" or "how the detailed description of the aristocratic banquet in the article reflects the social class differences of the time".
** 3. Scene Description **: Scene Description is the main means to portray characters, develop plots, and express the theme. The related topic might be "Analyzing the dual role of a scene description in promoting the plot and shaping the characters." For example, the description of a battle scene could show the bravery of the soldiers (shaping the characters) and push the story in the direction of victory or defeat (promoting the plot).

Vega saves the ball in a strange arcIn one game, Vega was defending from a corner kick. The moment he touched the ball, the ball formed a strange arc and flew high towards his own goal. At that time, the opponent launched a fierce attack. After the corner kick entered the penalty area, Vega quickly reacted to clear the siege. Although there were no obvious mistakes in his actions after the slow-motion replay, the ball's rebound angle and rotation speed were abnormal, which could be the result of multiple factors such as the slippery ground, the state of the ball, and the wind direction. Fortunately, the ball grazed the crossbar and flew out of the end line to avoid an own goal. If the ball had gone into the net, the psychological pressure on Vega would have multiplied, and the morale of the team might have been hit. However, Vega continued to play well in the subsequent games, and this incident also reflected his calmness and courage at the critical moment.
