        /* 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 {

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  ...

Java Static Initializer Block

Static initialization blocks are executed when the class is loaded, and you can initialize static variables in those blocks. It's time to test your knowledge of  Static initialization blocks . You can read about it  here. You are given a class  Solution  with a  main  method. Complete the given code so that it outputs the area of a parallelogram with breadth   and height  . You should read the variables from the standard input. If   or    , the output should be  "java.lang.Exception: Breadth and height must be positive"  without quotes. Input Format There are two lines of input. The first line contains  : the breadth of the parallelogram. The next line contains  : the height of the parallelogram. Constraints Output Format If both values are greater than zero, then the  main  method must output the area of the  parallelogram . Otherwise, pri...
