• 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

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.
