- Write a function called
rotatewhich takes an array and a number, and moves each element however many spaces the number is to the right. For the value at the end of the array,rotateshould move it back to the beginning.
rotate([1,2,3], 1) // [3,1,2] rotate([1,2,3], 2) // [2,3,1] rotate([1,2,3], 3) // [1,2,3]
- Write a function called
makeXOGridwhich takes in two parameters, rows and columns, and returns an array of arrays with the number of values in each subarray equal to thecolumnsparameter and the number of subarrays equal to therowsparameter. The values in the sub-arrays should switch between"X"and"O".
makeXOGrid(1,4) /*/ [["X","O","X","O"]] /*/ makeXOGrid(3,2) /*/ [["X","O"],["X","O"],["X","O"]] /*/ makeXOGrid(3,3) /*/ [["X","O","X"],["O","X","O"],["X","O","X"]] /*/
