Consider a scenario in which you would use recursive binary search. What would you do? What is the halting condition for a recursive binary search in the first place?
Explain the meaning of the recursion with a simple example
Iteration versus one-friend recursion.
1. Your job is to accept the tuple a1, a2,..., a and return the tuple an, an1,..., a1 that has been reversed. You will only take an element off of one end or put an element back on one end because you are being indolent. But you have allies in recursion who can assist you.Please include the recursive code as well as a paragraph with the friend's description of the algorithm.
2. Now imagine that you lack pals but have a stack. (Refer to Chapter 3. Quickly design an incremental programme to address this issue. Include loop invariants and other crucial stages that are necessary to describe an iterative algorithm.
3. Trace both of these scripts separately. Compare and contrast their computerised calculations step by step.
