Objective: implement a classic snake game.

• Write a C program snake that implements the classic snake game.
• The game must utilize all available space of the current terminal window.
• There must be a visible border delineating the area where the snake can move.
• The initial length of snake is one character.
• Initial direction of the snake's movement is chosen randomly.
• The user can press one of the four arrow keys to change the direction of the snake's movement.
• Trophies are represented by a digit randomly chosen from 1 to 9.
• There's always exactly one trophy at any given moment.
• When the snake eats the trophy, its length is increased by the corresponding number of characters.
• A trophy expires after a random interval from 1 to 9 seconds.
• A new trophy is shown at a random location on the screen after the previous one has either expired or is eaten by the snake.
• The snake's speed is increased in a linear proportion with its length.
• The snake dies and the game ends if:
  • It runs into the border; or
  • It runs into itself; or
  • The user attempts to reverse the snake's direction.
• The user wins the game if the snake's length grows to the length equal to half the perimeter of the border.

• A single C source code file with your work.
• A screenshot (in PNG or JPG format) showing a representative sequence of the gameplay.
