MODIFIED-BOTTOM-UP-CUT-ROD(p, n, c) to return not only the value but the actual solution, too. Hint: It is similar to how array s is maintained in EXTENDED-BOTTOM-UP-CUT-ROD. Now you need to initialize not just array r but also array s in EXTENDED-MEMOIZED-1 let r[0..n] and s[0..n] be new arrays2 r[0] = 03 for j = 1 to n4 q = p[ j ]5 s[ j ] = j6 for i = 1 to j - 17 if q < p[ i ]+ r[ j - i ] - c8 q = p[ i ]+ r[ j - i ] - c9 s[ j ] = i10 r[ j ] = q11 return r and s3

i don't understand really? can u provide more information

u should make a machine that can make ice cream fresh!
