Explore how to identify all missing numbers in an array consisting of integers from 1 to n. Learn to implement an efficient solution that runs in linear time with constant space, enhancing your problem-solving skills for coding interviews.
Statement
Given an array, nums, of n integers where nums[i] is in the range [1,n], return an array of all the integers in the range [1,n] that doesn’t appear in nums.
Constraints:
n=nums.length
1≤n≤103
1≤nums[i]≤n
Examples
Understand the problem
Let’s take a moment to make sure you’ve correctly understood the problem. The quiz below helps you check if you’re solving the correct problem:
