Binary search proof of correctness
WebI am trying move cursor to it's parent node in a binary tree. I want to do it recursively without using a keeping a node to keep track of the parent. I think my base/stoping case is correct but I believe the last two if statement is wrong. Im not sure on how to go about it. Any advice will be helpful. Thank you. WebNov 27, 2024 · Now we want to convince ourselves of the correctness of the method. a) Calculate prod (17,7) with the above algorithm. Specify the recursive calls. b) Show with full induction to k: For all k ∈ N and all x ∈ R the call prod (x,k) returns the return value x · k. please help solve this, i don't know where to even start. discrete-mathematics.
