Reduction Let M be the problem of multiplying the lower triangular matrix by the upper triangular matrix. Let M' the problem of multiplying two square matrices.

Let T(n) be the complexity of an optimal algorithm to solve M. Show that M is at least as difficult as M' in the sense that both have the same lower bound.
