add functions here:

slide_right (str, int, str) -> str The first parameter is the square being added to the game board. The second parameter is a row number and the third parameter is the string representation of a game board. Assume that the square, row number, and game board are valid. This function returns a string that is like the original game board, except that: - the square from the first parameter has been slid into the "beginning" (i.e., first column) of the given row number; - the square at the "end" (i.e., last column) has slid off the game board; - the remaining squares have slid to the right. slide_left (str, int, str) => str The first parameter is the square being added to the game board. The second parameter is a row and the third parameter is the string representation of a game board. Assume that the square, row number, and game board are valid. This function returns a string that is like the original game board, except that: - the square from the first parameter has been slid into the "end" (i.e., last column) of the given row number; - the square at the "beginning" (i.e., first column) has slid off the game board; - the remaining squares have slid to the left. slide_right (str, int, str) -> str The first parameter is the square being added to the game board.
