1. For the following program segment, fill in the tracing table below as described in the course notes. You should make a duplicate of this table in your homework submission.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

int x = 15, y=30, z=10, a=0; if ( x > y ) { if (x > z) { a = x; } else { a = z; } } else { if (y > z) { a = y; } else { a = z; } } System.out.println("The value is: "+a);

Statement	Program State
int x = 15, y = 30, z = 10, a = 0;
	x = y = z = a =
if ( x > y ) {
	x = y = z = a =
if (x > z) {
	x = y = z = a =
a = x;
	x = y = z = a =
} else {
	x = y = z = a =
a = z;
	x = y = z = a =
} } else {
	x = y = z = a =
if (y > z) {
	x = y = z = a =
a = y;
	x = y = z = a =

	x = y = z = a =
a = z;
	x = y = z = a =

	x = y = z = a =
System.out.println("The value is: " + a);
	x = y = z = a =

2.For the following program segment, fill in the trace table below with values as described in the course notes. You should make a duplicate of this table in your homework submission. In addition, write a single sentence in English summarizing what this code segment does:

1 2 3 4 5 6 7 8

int n = 9431; String output=""; while (n > 0) { int x = n % 10; output = output + x; n = n / 10; } System.out.println("Result is: "+output);

Statement	Program State
int n = 9431; String output = "";
	n = output =
while ( n > 0 ) {
	n = output =
int x = n % 10;
	x = n = output =
output = output + x;
	x = n = output =
n = n / 10;
	x = n = output =
}
	n = output =
System.out.println("Result is: "+output);
	out = "Result is: " n = output =
