Write a function named "shift_right" that takes as its arguments the following: (1) an array of floating point values; (2) an integer, call it "left", that tells the leftmost cell of the part of the array to be shifted; (3) an integer, call it "right", that tells the rightmost cell of the part of the array to be shifted; (4) a positive integer, call it "distance" that tells how many cells to shift by. The function should make sure that left is less than or equal to right, and that distance is greater than zero. If either of these conditions fails, the function should return the value 1 to indicate
