WebJul 15, 2024 · A Simple Solution is to linearly traverse the array and find the missing number. Time complexity of this solution is O (n). Below is the implementation From Mathematical formulae we know that in an AP, Sum of the n elements = (n/2) (a+l) n is the number of elements, a is the first element and l is the last element WebLike the brute-force approach, do a lookup for positive numbers in the hash set, starting from 1. The smallest positive number missing from the hash set is the result. The time complexity of this solution is O(n), but requires O(n) extra space for the hash set. Following is the C, C++, Java, and Python program that demonstrates it:
