Write a function called shifter that takes a 2d array inarray and i) creates an array circleft that contains the circular left shift by one position of all the columns of inarray in a 2d array, ii) creates an array called circup that contains the circular up shift by one position of all the rows of inarray, and iii) creates an array called circ2x that first circularly shifts the columns of inarray by one position, and with the resulting array, shifts all the rows up by one position. the function must operate on a 2d array of any size. hint: array indexing, single colon and end should be used.
