Reversing the Second Half: A sequence will be called a zig zag sequence if the first k elements in the sequence are in increasing order and the last k elements are in decreasing order, where k = ( n+1) /2 . A sequence will be called a zig zag sequence if the first elements in the sequence are in increasing order and the last elements are in decreasing order, where . Assume root is at level-1, zig-zag means that nodes at even levels will be printed left to right and the nodes at odd levels will be printed from right to left. Problem. ⭐️ Content Description ⭐️In this video, I have explained on how to debug zig zag sequence problem in hackerrank. a= [2, 3, 5, 1, 4] Now if we permute the array as [1, 4, 5, 3, 2], the result is a zig zag sequence. ANSWER: Debug the given function findZigZagSequence to return the appropriate zig zag sequence for the given input array. A sequence will be called a zig-zag sequence if the first k elements in the sequence are in increasing order and the last elements are in decreasing order, where k = (n +1)/2. You need to find the lexicographically smallest zig zag sequence of the given array. You cannot Jan 11, 2023 · Now if we permute the array as [1,4,5,3,2], the result is a zig zag sequence. The problem task is to debug code to permute an array into a zig zag sequence, where the first half of elements are in increasing order and the second half are in decreasing order. Given an array of n distinct integers, transform the array into a zig-zag sequence by permuting the array elements. Given an array of distinct integers, transform the array into a zig zag sequence by permuting the array elements. The middle element is swapped with the last element of the array to start forming the zig-zag pattern. Determine the minimum number of elements to delete from a sequence so its elements alternate between increasing and decreasing. Example. You switched accounts on another tab or window. Reload to refresh your session. Just below this, an example shows: """ Example. Aug 10, 2022 · Given an array of n distinct integers, transform the array into a zig-zag sequence by permuting the array elements. Today, we’re diving into the Zig Zag Sequence challenge, a fascinating problem that involves sorting and manipulating arrays You need to find the lexicographically smallest zig zag sequence of the given array. Note: You can modify at most three lines in the given code. Submissions. e. You signed out in another tab or window. This document provides solutions to the HackerRank Zig Zag Sequence problem in Python, Java, and C++. An array A is a zigzag array if either: * Every even-indexed element is greater than adjacent elements, ie. You signed in with another tab or window. Now if we permute the array as , the result is a zig zag sequence. The solutions include sorting the array, swapping elements to achieve the zig zag pattern, and outputting the You need to find the lexicographically smallest zig zag sequence of the given array.

In the provided example, the array [2, 3, 5, 1, 4] is sorted into [1, 4, 5, 3, 2]. However, based on my understanding of lexicographic order, wouldn't it be sorted into [1, 2, 5, 4, 3]? Is this example just illustrating a zig-zag sequence and not necessarily the lexicographically smallest zig-zag sequence?. Description of this problem is terrible and missleading: "You need to find the lexicographically smallest zig zag sequence" should be stated simply as "You need to find the zig zag sequence" why? the "lexicographically smallest zig zag sequence" of [1,2,3,4,5,6,7] could be [1,3,2] "Now if we permute the array as [1,4,5,3,2], the result is a zig zag Can you solve this real interview question?
