WebRunning time of binary search. Google Classroom. 32 teams qualified for the 2014 World Cup. If the names of the teams were arranged in sorted order (an array), how many items in the array would binary search have to examine to find the location of a particular team in the array, in the worst case? WebA Binary Search would require the data to be sorted in O(nlogn) and then searched O(logn). Therefore, the time complexity would be O(nlogn) + O(logn) = O(nlogn). Case 2: When the data is sorted, a Binary Search will be more time efficient as it will only take O(logn) time, while the Sequential Search will still take O(n) time.
