How do I make a zigzag array?

How do I make a zigzag array?

Given an array of DISTINCT elements, rearrange the elements of array in zig-zag fashion in O(n) time. The converted array should be in form a < b > c < d > e < f.

How do you create a zigzag array in Java?

1. // C code to display array into Zigzag fashion. Input- Enter the number of elements:7 Input the array elements: 1 2 3 4 5 6 7 Output- zigzag pattern of the array: 1 3 2 5 4 7 6.
2. // Java code to display array into Zigzag fashion.
3. a = int(input(“Enter the number : “))

How do I print a 2D array diagonally?

Start from the index (0,0) and print the elements diagonally upward then change the direction, change the column and print diagonally downwards. This cycle continues until the last element is reached. Algorithm: Create variables i=0, j=0 to store the current indices of row and column.

How do you print the diagonal of a matrix?

1. For Principal Diagonal elements: Run a for a loop until n, where n is the number of columns, and print array[i][i] where i is the index variable.
2. For Secondary Diagonal elements: Run a for a loop until n, where n is the number of columns and print array[i][k] where i is the index variable and k = array_length – 1.

What is a triplet in an array?

Examples: Input: array = {12, 3, 4, 1, 6, 9}, sum = 24; Output: 12, 3, 9. Explanation: There is a triplet (12, 3 and 9) present. in the array whose sum is 24.

What is the Order of elements in a zig zag array?

In short, the order of elements in the output zig-zag array would be [1st < 2nd > 3rd < 4th > 5th < 6th > 7th]. Therefore, if the given input array is [4, 3, 7, 8, 6, 2, 1], one of the arrangement in zig-zag array would be [3, 7, 4, 8, 2, 6, 1]. Few points worth mentioning here before we proceed towards thinking how to solve it efficiently.

When is an array of distinct integers zigzag?

We say an array of distinct integers, , is zigzag if no three consecutive elements in the array are either increasing or decreasing. In other words, if there are three elements , , in the array such that or , the array is not zigzag.

How to arrange an array of integers in order?

Basically, we are given an array of integers and we need to arrange this array in an order such that 1st element is lesser than 2nd element, 2nd element is greater than 3rd element, 3rd element is lesser than 4th element, 4th element is greater than 5th element, so on.
