Below is the implementation … WebJun 24, 2024 · An Efficient Solution can count triplets in O (n 2) by sorting the array first, and then using method 1 of this post in a loop. 1) Sort the input array in increasing order. 2) Initialize result as 0. 3) Run a loop from i = 0 to n-2. An iteration of this loop finds all triplets with arr [i] as first element.

If you want to get 7, you would have to ... WebHere's the pseudocode for binary search, modified for searching in an array. The inputs are the array, which we call array; the number n of elements in array; and target, the number being searched for. The output is the index in array of target: Let min = 0 and max = n-1. Compute guess as the average of max and min, rounded down (so that it is ...
