Count the number of possible triangles
WebSep 14, 2024 · How to count the number of possible triangles? Following are steps to count triangle. Sort the array in ascending order. Now run a nested loop. The outer loop runs from start to end and the innner loop runs from index + 1 of the first loop to the end. Take the loop counter of first loop as i and second loop as j. Take another variable k = i + 2 WebCount Possible Triangles. easy. Prev Next. Given an unsorted array arr [] of n positive integers.

Share. harvey centre cineworldWebEach edge is determined by two vertices, so the total number of pairs of edges is: ( n 2) = n! 2! ( n − 2)! = n ( n − 1) 2 Which is the answer you provided. Note that this chooses 3 points out of n, but these points may be colinear, so if you don't consider those as triangles you'll have to subtract them from the total count.
