Interval Inversion Count Given an array of length n with elements bounded by a small constant (≤ 50), we need to answer m queries of the form: count the number of inversions inside subarray [l, r]. A naive O(n2) per query is too slow, and a Mo’s algorithm solution, while feasible for moderate constr...

Problem Analysis and Solution Approach Handling Large Input Values The problem presents a challenging constraint where values can reach up to 264, exceeding typical integer limits. Since the solution depends only on the count of distinct digits in each number rather than the actual values, we can pr...
