This variant has been used to identify biologically … WebSo the algorithm calculates in a top down approach the maximum revenue for rod length 1,2,3 to get the final answer. The recursion tree would explain it more clearly. The recursion tree shows a recursive call resulting from rodCutting(price,4). This figure clearly explains why the computation time for the algorithm is so ridiculous.
