Binary Search

beginnerlayer B6 · Binary search5 tests

You are given an array nums sorted in strictly increasing order and a value target. Return the index at which target sits, or -1 if it is not in the array.

  • The array may be empty
  • All values are distinct
  • Your solution must run in O(log n) time — a linear scan does not count
