[LeetCode] 1899. Merge Triplets to Form Target Triplet A triplet is an array of three integers. You are given a 2D integer array triplets, where triplets[i] = [ai, bi, ci] describes the ith triplet. You are also
Given an unsorted array return whether an increasing subsequence of length 3 exists or not in the array. Formally the function should: Return true if there existsi, j, k such thatarr[i]<arr[j]<arr[k]given 0 ≤i<j<k≤n-1 else return false. Your algorithm should run in O(n) time...
