To get a chance to participate in this coding rounds, we were asked to fill forms . the candidates and were short listed here on the basis of pointer ( 7.5 and above were all selected, for people with pointer 7 to 7.5, there projects and internships were taken into consideration to be allowed to appear in this round) 3 CODING questions in 90 mins on hackerrank. Q1 ) Was a simple question, all you had to do was find a PnC formula and just put the values in it to get the answer. Q2)Was based on array . This was a medium level question, 7/11 test case passed using brute force (O(n^2)). An accurate solution of which is actually in O (n), but i modified my code and managed to get all the 11 test cases right using just a slight modification in my brute force approach! Q3)A matrix was given, the solution to which was by applying BFS on it but not exactly that. I could not understand the problem enough as I was running out of time ! The name of the Question was "Marathon" and said was a lot similar to some other famour problem named "Rat in a maze".
