@vikanshu2016
hello vikanshu,
pls watch video tutorial again and try to debug ur code. if u still not able to find ur mistake then pls ask
if have tried debugging but failed
it is working for 2x2 matrices but when it comes to 3x3 or more it is showing wrong output and output is always less than the expected outcome.
input:-
arr = 3x3 matrix of all 1
output = 93
expected output = 100
arr = 4x4 matrix of all 1
output = 336
expected output = 400
I have tried running in debug mode but unable to find error and logic is according to the video.
