Sum of all submatrices approach 1

[vaishnavtannu (Vaishnavi Singh)]

In the video lecture, it is being written

for(int li = 0; li < n-1; li++)
for(int lj = 0; lj < n-1; lj++)
for(int bi = li+1; li < n-1; li++)
for(int bj = lj+1; li < n-1; li++)

For the bottom right, why it’s starting from li + 1 or lj + 1 ?
To consider a submatrix containing a single cell, why we are not starting from li and lj itself ?

@vaishnavtannu

for(int bi = li+1; li < n-1; li++)
for(int bj = lj+1; li < n-1; li++)

yeah u r right . it should start from li and lj.
