questions and problems will cover all of the following concepts (each c
includes at least one example question):

1. trace and evaluate assignment sequences

what will be the output of this code?
int x = 2;
int y = 10;
x = y + 1;
y = x - 1;
x = x + 1;
y = y - 1;
x = x - y;
system.out.print(x);

Explanation:

Step1: Initialize variables

$x = 2$, $y = 10$

Step2: Update x with y+1

$x = 10 + 1 = 11$

Step3: Update y with x-1

$y = 11 - 1 = 10$

Step4: Increment x by 1

$x = 11 + 1 = 12$

Step5: Decrement y by 1

$y = 10 - 1 = 9$

Step6: Update x with x-y

$x = 12 - 9 = 3$

Step7: Output the final x value

System.out.print(x) outputs the current x.
