1632. Rank Transform of a Matrix

Given an m x n matrix, return a new matrix answer where answer[row][col] is the rank of matrix[row][col]. The rank is an integer that represents how large an element is compared to other elements. It is calculated using the following rules: - The rank is an integer starting from 1. - If two elements p and q are in the same row or column, then: - If p < q then rank(p) < rank(q) - If p == q the
