WebNov 7, 2024 · Binary search can be applied to none array problems, such as Math, and this statement is still valid. For example, In LeetCode 35, the question asks us to find an index to insert into the array. It is possible that we insert after the last element of the array, thus the complete range of boundary becomes let lo = 0, hi = nums.length; 2.
