Iterative method: In this method, the iterations are controlled through looping conditions. The space complexity of binary search in the iterative method is O(1). Recursive method: In this method, there is no loop, and the new values are passed to the next recursion of the loop. Here, the...

Given a non-empty binary search tree and a target value, find k values in the BST that are closest to the target.
32 is good enough for not less amount of problems. Let me give an example: what if we have binary search in binary search and a heavy check function? Then this approach is ~40 times (200 * 200 / (32 * 32)) faster. -C++ black magic ...
The iterative version of the algorithm involves a loop, which will repeat some steps until the stopping condition is met. Let’s begin by implementing a function that will search elements by value and return their index:Python def find_index(elements, value): ......
