2117. Abbreviating the Product of a Range

You are given two positive integers left and right with left <= right. Calculate the product of all integers in the inclusive range [left, right]. Since the product may be very large, you will abbreviate it following these steps: - Count all trailing zeros in the product and remove them. Let us denote this count as C. - For example, there are 3 trailing zeros in 1000, and there are 0 trailing
