text: If the length of the rod is less than the maximum length , Max_lene will consider it . Now depending upon the profit , either Max_lene we will take it or discard it .
code: if ( length [ n - 1 ] <= Max_len ) { t [ n ] [ Max_len ] = Math . max ( price [ n - 1 ] + un_kp ( price , length , Max_len - length [ n - 1 ] , n ) , un_kp ( price , length , Max_len , n - 1 ) ) ; }
