Smallest positive integer codility
WebbThe problem is to find the smallest positive integer that does not occur in a given array. The main strategy is to use two java.util.TreeSets, which order their elements: 1) a perfect set and 2) the actual set and check for the missing element in the actual set that exists in the perfect set. TestNG test cases for this problem which all passed: 1 2 Webb13 feb. 2024 · We have to find the smallest positive number, so we may ignore all the negative numbers and start searching from the smallest positive integer that is 1 and so on. Note that we are not considering the integer 0 while finding the smallest positive number. We will start searching from integer 1. If the input array is:

We’re supposed to return the smallest positive non-zero integer that does not occur in the array. WebbThe idea is to insert all elements (or only positive integers) in the array into a hash set. Like 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 ...
