Use basic arithmetic operations (+-*/) to implement sqrt function.
Given N credits cards, determine if more than half of them belong to the same person/owner. All you have is an array of the credit card numbers, and an api call like isSamePerson(num1, num2).

Question is verbose, uses search engine, string matching etc., but at the end boils down to this: There is two dimensional array where each sub array (row) is sorted, i.e. [[1 1000 2000] [20 10001 5000] [55 10002 222222]] Find a minimum range contain a number from each row. For above array it should be (1000-1002) range.

Given an array of strings with commit ids, and a predicate isBuggy that returns if a single commit is buggy, write a program that finds the first buggy commit. - When a commit is buggy, we assume that all its children are buggy. - When a commit is not buggy, we assume that all its ancestors are not buggy. After solving it, I had to describe its time complexity and spatial complexity and how would I choose the test cases.
Determine if a string is valid based on placement of parenthesis. i.e. "123(13(44))" is valid but ")234(12)(" is not.
