Exercise P6.5. Write a function vector merge (vector a, vector b) that merges two arrays, alternating elements from both arrays. If one array is horter than the other, then alternate as long as you can and then appen remaining elements from the longer array. For example, if a is 1 4 9 16 and b is 9 7 4 9 11 then merge returns the array 1 9 4 79 4 16 9 11
