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.
Problem. 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 in nums.
The Missing Number LeetCode Solution – “Missing Number” states that given an array of size n containing n distinct numbers between [0,n]. We need to return the number which is missing in the range.
The task is to find the repeating and missing numbers a and b. Return a 0-indexed integer array ans of size 2 where ans [0] equals to a and ans [1] equals to b. Example 1: Input: grid = [ [1,3], [2,2]] Output: [2,4] Explanation: Number 2 is repeated and number 4 is missing so the answer is [2,4].
