In [ ]: 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). let count 123 1 = (* YOUR CODE HERE *) In [ ]: assert (count123 [3; 4; 2; 1;3] = (1,1,2))

Follow-up Question
Could you implement this in OCAML:
Here's the question again:
Write a function: count123:intlist->int*int*int
that takes in an int list l and returns a 3-tuple of integers counting the number of 1's, 2's and 3's respectively in l. For example, count123 [3;4;2;1;3] = (1,1,2), and count123 [4;4;1;2;1] = (2,1,0).
In [ ]:
letcount123l=(* YOUR CODE HERE *)
In [ ]:
assert (count123 [3;4;2;1;3] = (1,1,2)).
The code in Python is in the attached image, which needs to be implemented in OCAML.
Thanks!
