Binary search in vector c++
WebWith a binary search, unless your item is going to end up being the first or last item in the list, your conditional result is going to be randomized. Roughly half the time the branch-predictor will have gotten it wrong and will have to flush the instruction pipeline refill it with the right branch. WebWe can search a pair in a sorted vector of pairs by using the built-in function “binary_search ()”of STL library. Syntax of the function:- binary_search (start_address, …
