WebJul 18, 2024 · Binary search algorithms are also known as half interval search. They return the position of a target value in a sorted list. These algorithms use the “divide and conquer” technique to find the value's position. Binary search algorithms and linear search algorithms are examples of simple search algorithms. WebAug 27, 2024 · The approach is to have 1 for loop to go from 1 to 1000, and 1 counter that counts the current total missing integer. Once the counter equals k in the for loop, that index i of the for loop is the answer.
