Problem 1 Write a function count123: int list -> int * int * int that takes in an int list 1 and returns a 3-tuple of integers counting the number of 1's, 2's and 3's respectively in 1. For example, count123 [3;4;2;1;3] = (1,1,2), and count123 [4; 4; 1; 2; 1] = (2,1,0). In [] let count123 1 = (* YOUR CODE HERE *) In [] assert (count123 [3; 4; 2; 1;3] = (1,1,2))
