Binary search predicate function
WebBinary Search Intuition. The key idea is to notice that comparing the elements of the array to the first element leads towards fining the point of rotation; The element in the point of rotation is the smallest element, since it the point from where the original ( non - rotated ) array starts. And since the array is sorted it is the smallest one.

WebAug 29, 2024 · Finding the insertion index. A common feature of binary search functions in standard libraries is that when the target is not found, then return an -1 -insertAt , where insertAt is the position where the value could be inserted to preserve the correct ordering.

WebA predicate is a statement or mathematical assertion that contains variables, sometimes referred to as predicate variables, and may be true or false depending on those variables’ value or values. In propositional logic, atomic formulas are sometimes regarded as zero-place predicates. [1] In a sense, these are nullary (i.e. 0- arity) predicates. WebMar 14, 2024 · Well, the other answers have helped to solve the issue, but in case you didn't know, there are built-in functions for performing binary search in C++ that you can use them..
