Web1. The function cut_rod takes two arguments, the list of prices, p and the length of the rod, n. 2. cut_rod creates two lists r and s. 3. r[i] is the maximum revenue we can earn and s[i] is the length of the first piece to cut from a rod of length i. 4. The list s will be used to figure out how to cut the rod to get maximum revenue. WebNov 11, 2024 · 12. Explanation 1: Cutting the rod into 2 rods of length 2 and 6 gives us a cost of 3 + 9 = 12, which is optimal. Input 2: n = 4, prices [] = [1, 1, 1, 6] Output 2: 6. Explanation 2: It can be seen that performing no cuts and taking the entire rod as a whole can lead to the optimal answer of 6.
