    I did, infact the code is giving correct output when i am running it on my device on the sample tests, but the online judge is giving RA verdict.

Why if(i>1){ and if(j>1){ ?

I think that ifs have to be remove, then it should work.

      Consider the first if, if(i>1)...

      Inside of that if you have if(mtr[i][j]) dp[i][j][1]=max(dp[i][j][1],mx+mtr[i][j]);

      Why you should ignore the mtr[][] values of first row?

        Because those cases are being included in "if(j>1)".

          Ok, that one if(mtr[i][j]) dp[i][j][1]=max(dp[i][j][1],mx+mtr[i][j]);

          Again, why the if? What if mx!=0 and mtr[i][j]==0?
