Online Assessment : Consists of some multiple-choice questions and the coding question of medium difficulty

Technical Round-1:Face to Face interview

• It basically consists of two coding questions:-
  • https://www.geeksforgeeks.org/problems/pascal-triangle0652/1 .He asked me to write both(brute and better) the approaches 
  •  Given an M × N matrix consisting of only 0 or 1, change all elements of row i and column j to 0 if cell (i, j) has a value of 0. Do this without using any extra space for every (i, j) having value 0.

First I had told the brute force approach and then he asked me to optimize it and then I used the in-place technique and he was satisfied with the answer, he asked me to write the code
