@Ramakan: for j=0 to col arr[0][j]=0;
for i=0 to rows arr[i][0]=0; assuming that given matrix is surrounded by 0 i.e indexs (i,j) for arr[][] will start from i=1 <= row and j=1 <= col. i guess your approach will work. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
