Java String Reverse

A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward.(Wikipedia)

Given a string , print Yes if it is a palindrome, print No otherwise.
Constraints
  •  will consist at most  lower case english letters.
Sample Input
madam
Sample Output
Yes
import java.io.*;
import java.util.*;

public class Solution {

   public static void main(String[] args) {
        
        Scanner sc=new Scanner(System.in);
        String A=sc.next();
        /* Enter your code here. Print output to STDOUT. */
        String result ="Yes";
        int length = A.length();
        for (int i=0; i<length/2;i++){
            if(A.substring(i,i+1).equals(A.substring(length-i-1,length-i))) {         
            }else {
             result ="No";
            }
        }
        System.out.println(result);
    }

Java Loops II print each element of our series as a single line of space-separated values.

We use the integers  ,  , and   to create the following series: You are given   queries in the form of  ,  , and  . For each query, print the series corresponding to the given  ,  , and   values as a single line of   space-separated integers. Input Format The first line contains an integer,  , denoting the number of queries.  Each line   of the   subsequent lines contains three space-separated integers describing the respective  ,  , and   values for that query. Constraints Output Format For each query, print the corresponding series on a new line. Each series must be printed in order as a single line of   space-separated integers. Sample Input 2 0 2 10 5 3 5 Sample Output 2 6 14 30 62 126 254 510 1022 2046 8 14 26 50 98 Explanation We have two queries: We use  ,  , and   to produce some series  : ... and so on. Once we hit  , we print the first ten terms as a single line of space-separate

Java Currency Formatter Solution

Given a  double-precision  number,  , denoting an amount of money, use the  NumberFormat  class'  getCurrencyInstance  method to convert   into the US, Indian, Chinese, and French currency formats. Then print the formatted values as follows: US: formattedPayment India: formattedPayment China: formattedPayment France: formattedPayment where   is   formatted according to the appropriate  Locale 's currency. Note:  India does not have a built-in Locale, so you must  construct one  where the language is  en  (i.e., English). Input Format A single double-precision number denoting  . Constraints Output Format On the first line, print  US: u  where   is   formatted for US currency.  On the second line, print  India: i  where   is   formatted for Indian currency.  On the third line, print  China: c  where   is   formatted for Chinese currency.  On the fourth line, print  France: f , where   is   formatted for French currency.

Java Substring Comparisons

We define the following terms: Lexicographical Order , also known as  alphabetic  or  dictionary  order, orders characters as follows:  For example,  ball < cat ,  dog < dorm ,  Happy < happy ,  Zoo < ball . A  substring  of a string is a contiguous block of characters in the string. For example, the substrings of  abc  are  a ,  b ,  c ,  ab ,  bc , and  abc . Given a string,  , and an integer,  , complete the function so that it finds the lexicographically  smallest  and  largest substrings of length  . Input Format The first line contains a string denoting  . The second line contains an integer denoting  . Constraints  consists of English alphabetic letters only (i.e.,  [a-zA-Z] ). Output Format Return the respective lexicographically smallest and largest substrings as a single newline-separated string. Sample Input 0 welcometojava 3 Sample Output 0 ava wel Explanation 0 S
