Well a "double" pointer (A more accurate term is multidimensional pointer,
in this case a two dimensional pointer) is basically a pointer to an array
of pointers.
So, int **ptr basically says, ptr is a pointer to an array of pointers. And
you can allocate memory to each of these pointers individua
int **x;
x = new int*[n];
for (int i = 0; i < n; i++){
x[i] = new int[m];
}

Heres a problem that I've been trying to solve using Dynamic
Programming but I've got no where with it. Any hints would be
appreciated.
A program's library offers a simple function to split a string into
two parts. As this operation requires copying the entire string, it
takes time n, where n is t

I didnt quite get this problem. Sample case?

It is NOT possible to multiply two matrices in less than O(n^2) simply
because there are n^2 elements, and you got to "touch" all of them at
least once!

Try using Strassen's Matrix Multiplication Algorithm.
