Webm (m+1)/2 is the amount of all concatenated arrays. And (m−countx) (m−countx+1)/2 is the amount of all concatenated arrays which don't have x. in m arrays we have countx arrays that have x .If x doesn't appear in concatenated arrays , the 2 arrays must be chosen from (m-countx) arrays which don't have x. → Reply.

WebApr 11, 2024 · The longest common prefix is: gee. Time Complexity: O (MAX * n * log n ) where n is the number of strings in the array and MAX is the maximum number of characters in any string. Please note that comparison of two strings would take at most O (MAX) time, and for sorting n strings, we would need O (MAX * n * log n ) time. Auxiliary …
