WebDec 15, 2024 · Time and again, the candidates send out the same resume for different job profiles. However, a one-type-fits-all resume reduces your chances of being selected for the befitting job profiles. So, if you are being rejected repeatedly, it might be that the skills and experience in your resume do not match the requirements in the job posting. WebThe best case for binary search is we find the target on the very first guess. That takes a constant amount of time. So, in the best case binary search is Ω(1), O(1), which also means it is Θ(1). On the other hand, in the worst case, where we don't find the target, binary search is Ω(log(n)), O(log(n)), which also means it is Θ(log(n)).

WebThe time complexity of creating these temporary array for merge sort will be O(n lgn). Since, all n elements are copied l (lg n +1) times. Which makes the the total complexity: O(n lgn) + O(n lgn) = O(2n lgn). And we know that constants doesn't impact our complexity substantially. So time complexity will still be O(n lgn).
