Trace the following pieces of code and give their exact output and the tracing steps.
a.
String [] letters={"GHI","VWX","YZ&", "JKL","MNO", "ABC","STO", "DEF", "PQR"};
int n = 0;
for (int i = letters.length-3; i > 0; i--) {
System.out.printf("%s\n", letters (i].charAt (n++));
if (n > 2) n 0;
int [] array = (12,9,1,2,11,8,10,7,3};
System.out.println(array[array[3]-array[2]] *4);
b.
String sentence "Spring2020TM105FinalExamTakeHomeExam";
int someVariable = sentence.length () -2;
do {
if (someVariable < 1) break;
System.out.println (sentence.charAt (someVariable+l1));
someVariable - 6;
while (someVariable >= 1);
System.out.println ("some Variable =
+ someVariable);
