Guide In the AWK series, let's take a look at the next command, which tells Awk to skip all the remaining patterns and expressions you have provided, and process the next input line directly. The next command helps you prevent unnecessary steps

Given an integer n, generate all structurally unique BST's (binary search trees) that store values 1 ... n.For example,Given N = 3, your program should return all 5 unique BST ' s shown below. 1 3 3 2 1 \// /\

Given an unsorted array of integers, find the length of longest increasing subsequence.For example,Given [10, 9, 2, 5, 3, 7, 101, 18] ,The longest increasing subsequence [2, 3, 7, 101] is and therefore the length is 4 . Note that there could be more

Given a binary tree, return the level order traversal of its nodes ' values. (ie, from left-to-right, level by level).Given binary Tree {3,9,20,#,#,15,7} , 3 / 9 / 7Return[ 3], [9,20], [15,7]]So utilizing queue.size () before remove

Given N, how many structurally unique BST's (binary search trees) that store values 1 ... n?For example,Given N = 3, there is a total of 5 unique BST ' s. 1 3 3 2 1 \// /\ 3 2 1 1 3 2 /
