One Player, One Move



The rst part (onePlayerOneMove in the le csce322assignment02part01.js) will take in one




argument (a game) and return a function that takes in one (1) argument (a move), and returns the game that is the result of Player 1 dropping a 1 into the column of the game denoted by the move. The 1 should fall (move down through the -’s in the column) until it reaches a space that is not - or reaches the last row in the game. An example is provided below

One Player, Many Moves



The second part (onePlayerManyMoves in the le csce322assignment02part02.js) will take in one (1) argument (a game) and return a function that takes in one (1) argument (an arry of moves), and returns the game that is the result of Player 1 playing each move in succession (following the rules of onePlayerOneMove) until all of the moves in the array have been played, or Player 1 has placed four (4) 1’s in a row horizontally, vertically, or diagonally.

Many Players , One Move



The third part (manyPlayersOneMove in the le csce322assignment02part03.js) will take in one




argument (a game) and return a function that takes in one (1) argument (an arry of moves), and returns the game that is the result of each player in the game making exactly one move until each player has completed a move or a player has won the game (placed four of their pieces vertically, horizontally, or diagonally). Player 1 places 1s, Player 2 places 2s, etc. (you may assume the highest number in the provided game is the number of players in the game). The moves are made in the order they appear in the moves array.

Many Players , Many Moves



The fourth part (manyPlayersManyMoves in the le csce322assignment02part04.js) will take in one (1) argument (a game) and return a function that takes in one (1) argument (an arry of moves), and returns the game that is the result of each player in the game taking turns making a move until all of the moves in the array have been exhausted or a player has won the game (placed four of their pieces vertically, horizontally, or diagonally). Player 1 places 1s, Player 2 places 2s, etc. (you may assume the highest number in the provided game is the number of players in the game).
