1.Create a function that transform an array from rows to columns.
2.Create an array,using the if statement find out if
the numbers of dimensions is correct.
3.Convert a list into an array and add two brackets to that new array.
4.Create two 2-d arrays and multiply each of them.
5.Create a right side triange pattern using the dollar sign'$'
