Write C program p1.c which implements and tests function rotate_left that shifts all elements of a non-empty int array A one location to the left, and stores the original left-most entry into the right-most position Example: A[] before call: A[] after call: 123456 2 3 4 5 6 1 after another call: 3 4 5 6 12 Test your function using a couple of test cases in function main, including one which calls rotate_left on an n-element array, containing numbers 1..n, n times and checks whether the resulting array is the same as the one you started with List your test cases together with the outputs in a comment at the end of your program Also, comment your program and format it well
