Find Missing and Repeated Values. Easy. You are given a 0-indexed 2D integer matrix grid of size n * n with values in the range [1, n 2]. Each integer appears exactly once except a which appears twice and b which is missing. The task is to find the repeating and missing numbers a and b.
Missing Number - Given an array nums containing n distinct numbers in the range [0, n], return the only number in the range that is missing from the array. Example 1: Input: nums = [3,0,1] Output: 2 Explanation: n = 3 since there are 3 numbers, so all numbers are in the range [0,3]. 2 is the missing number in the range since it does not appear ...
Jul 18, 2024 · One number from set {1, 2, …n} is missing and one number occurs twice in the array. Find these two numbers. Examples: Input: arr [] = {3, 1, 3} Output: Missing = 2, Repeating = 3. Explanation: In the array, 2 is missing and 3 occurs twice. Input: arr [] = {4, 3, 6, 2, 1, 1} Output: Missing = 5, Repeating = 1.
Find the Duplicate Number - Given an array of integers nums containing n + 1 integers where each integer is in the range [1, n] inclusive. There is only one repeated number in nums, return this repeated number.
