Java Program to find the Last Index of a Particular Word in a String - In Java, a string is also an object. It is the object of the String class. A String is a sequence of characters. The last index of a particular word in a string is nothing but the pos
Java String Java Characters Math 1. Overview In this tutorial, compare ways to find the longest substring of unique letters using Java. For example, the longest substring of unique letters in “CODINGISAWESOME” is “NGISAWE”. 2. Brute Force Approach Let’s start with a naive approach. To...
A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward as forward, such as madam. Write a java program to find the longest palindrome present in a given string. For example, in the string <span class="ant">a

This article demonstrates methods to find a given substring in a string in C++. The most straightforward way of solving the issue is thefindfunction, which is a built-instringmethod, and it takes anotherstringobject as an argument. #include<iostream>#include<string>using std::cin;using std::...
In this tutorial, you’ll learn how to find the first repeating character in a string in C++. You will learn three approaches to fulfill this purpose: the hashing technique, the brute-force method, and the writing of your algorithm.
Fill in the blank. Arrays can reduce the number of ___ needed in a program because of a single array instead of a collection of simple variables to store related data. How to get rid of white space at the end of the string in python? Explain how...
