nrows: number of rows
ncols: number of columns

int **arra = (int **)malloc( sizeof(int*) * nrows );
int *ar = (int *)malloc( sizeof(int) * nrows * ncols );
for( int a = 0; a  nrows; a ++ ) {
arra[a] = ar + ncols * a;
}

now index of array i and j can be accessed as arra[i][j]

@Navin: as you say you have to take stack or some other data structure 
then it will definately not be donw in O(1) space complexity i think the 
recursive solution is best because we are not explicitly using any extra 
space its internal stack is using this space.
