NettetIn the end, we will have only one element which does not have its pair and hence our single number. The space complexity of this approach is O (n) as we are using a set to store the elements. The time complexity is O (n) as we need to iterate through the array once. To code this approach we will first initialize a HashSet. exporting from zmod to blenderNettet13. aug. 2024 · Solution Approaches. 1. Using Brute Force.
