Q$6$A$-$

Solve $(x-5)6{!}^{**}7!$ Also solve $x^{{?}^{{?}^{?}}}{x}^{{?}^{{?}^{?}}}n=n$

Q$6$B$-$ Knapsack problem

Given a set of items, each with a weight and a value, determine which items to include in the collection so that the total weight is less than or equal to a given limit and the total value is as large as possible.

For example, there are $10$ different items and the weight limit is $67.$ So$,w[1]=23,w[2]=26,w[3]=20,w[4]=18,w[5]=32,w[6]=27,w[7]=29,w[8]=26,w[9]=30,w[10]=27$

$v[1]=505,v[2]=352,v[3]=458,v[4]=220,v[5]=354,v[6]=$

$414,v[7]=498,v[8]=545,v[9]=473,v[10]=543$
