For a given positive integer X we can obtain the reversed positive integer Rev(X) by reversing the order of X's digits and removing leading zeroes. For example, if X = 123 then Rev(X) = 321; and if X = 100, then Rev(X) = 1.
You will be given two positive integers x and y. Return their reversed sum, which is defined as Rev(Rev(x) + Rev(y)).
|-||x and y will each be between 1 and 1000, inclusive.|
