text: place parenthesis at different places between first and last matrix , recursively calculate count of multiplications for each parenthesis placement and return the minimum count
code: for k in range ( i , j ) : NEW_LINE INDENT count = ( MatrixChainOrder ( p , i , k ) + MatrixChainOrder ( p , k + 1 , j ) + p [ i - 1 ] * p [ k ] * p [ j ] ) NEW_LINE if count < _min : NEW_LINE INDENT _min = count NEW_LINE DEDENT DEDENT
