Read MoreJava program to check order of characters in string
You are given a String, your task is to write a program in Java that checks the order of its characters. If the order is previously defined, you have to check if the characters are in the given order otherwise check for alphabetical order. Let's understand the problem statement with an example − Example Scenario: Input: str = "abcmnqxz"; Output: res = TRUE The given string is in alphabetical order. Using Iteration In this approach, use a for loop to iterate over the string and check if the value of character at the current place and the previous ...
Read MoreJavaScript Sum odd indexed and even indexed elements separately and return their absolute difference
For a given list of elements, write a JavaScript program to find the sum of its odd and even indexed elements and then, calculate difference between them. To solve this problem, we will first separate odd indexed and even indexed elements. After separating them find their sum separately and store it in different variables. Now, we will calculate the difference between these sums to get desired result. Example Scenario: Input: list = [11, 21, 31, 41, 51, 61]; Output: difference = 30 Here, odd-indexed items are [21, 41, 61] and their sum is 123. The even-indexed items are ...
Read MoreJavaScript function to take a number n and generate an array with first n prime numbers
We are required to write a JavaScript function that takes in a number n and returns an array that contains first n prime numbers. We know that prime numbers are those numbers that are only divisible by 1 and themselves like 2, 3, 19, 37, 73 etc. Let's understand the problem with an example − Input: n = 6; Output: prime_numbers = [ 2, 3, 5, 7, 11, 13 ] Using Iteration We will first write a function that checks whether a given number is prime or not and then run a loop till the given number n ...

Read MoreJava program to find longest common prefix using word by word matching
In this article, we will explore how to find the longest common prefix among a given set of strings using two different approaches in Java. We will first discuss an approach that compares all strings directly to find the longest prefix and then move to a word-by-word matching approach. Problem Statement We are given a set of strings and we have to find the common prefix among all of them. A prefix is a substring for a string that contains the zero index and could be of any length from 1 to a complete string. Input 1 string arr[] = ...
