Samsung Noida R & D came to our campus for SLI+FTE.
Round 1: Coding Round
It was a 3 hours coding round which had one question to solve and the maximum number of submissions allowed was 50, but we could compile it as much as we want. No STL is allowed.
The question was :
A binary matrix of nxm was given, you have to toggle any column k number of times so that you can get the maximum number of rows having all 1’s.
for eg, n=3, m=3,
1 0 0
1 0 1
1 0 0
if k=2, then we will toggle column 2 and 3 once and we will get rows 1 and 3 with 1 1 1 and 1 1 1 i.e. all 1’s so answer is 2 as there are 2 rows with all 1’s.
if k=3, then we will toggle column 2 thrice and we will get row 2 with 1 1 1 i.e. all 1’s so answer is 1 as there is 1 row with all 1’s.
Only those students who passed all the test cases were shortlisted for the interviews.
Round 2: Technical Interview
This round lasted for about 30-45 minutes.
