Solution: Kth Smallest Number in Multiplication Table

Understand how to find the kth smallest element in an m by n multiplication table without constructing it explicitly. This lesson teaches you to use binary search combined with counting elements less than or equal to a candidate value, leveraging the table's ordered structure to optimize performance. You will learn the solution's reasoning, algorithm steps, and analyze its time and space complexity for efficient implementation.

Statement

You are given a multiplication table of size m×\timesn, where each element at position mat[i][j] is calculated as i×ji \times j ...
