Web27 aug. 2024 · Initialize two pointers i and j to first and second elements respectively, and initialize count of triangles as 0. Fix i and j and find the rightmost index k (or largest arr[k]) such that arr[i] + arr[j] > arr[k]. The number of triangles that can be formed with arr[i] and arr[j] as two sides is k – j. Add k – j to count of triangles.
