[Note: There maybe more than one error in each piece of code. a) int x = 1, total; while (x <= 10) { total += x; ++x; } b) while (x <= 100) total += x; ++x; c) public class Mystery { public static void main(String[] args) { int x = 1; int total = 0; while (x <= 10) { int y = x * x; System. out. println(y); total += y; ++x; }// end of while System. out. printf("Total is %d%n", total); }//end of main }//end of class Mystery2 Q2 What does the following program print? public class Mystery3 { public static void main(String[] args) { int row = 10; while (row >= 1) { int column = 1; while (column <= 10) { System. out. print(row % 2 == 1 ? "<" : ">"); ++column; }// end of while column<=10 --row; System. out. println(); }//end of while }//end of main }// end of class Mystery3
