WebFenwick Tree Fenwick is also called Binary indexed tree. It is easy to code , with same time complexity and space as the segment tree.We have a bit array which is fenwick tree for us where we store the sum of the elements depending upon Least significant bit mechanism. BIT Array : WebThen you read the input and every number you read, you insert it in the first position in S which contains an element greater than it (you can perform this with binary search). If you proceed in this way, S (not including the INFs) keeps the following properties at every step: - It is an increasing subsequence; irc §662 a 1 treas. reg. §1.662 a -2
