Answer #1

Question -1 -->

Answer is A

here, x = 10 and while loop continues till the value of x is greater than 0

so, first it will print 10 on the screen, and then the line is changed,

and then, x- = 3 ==> x = x - 3 ==> x = 10 - 3 = > x =7

so, loop will continue,

now, it will print 7 on the screen and then the line will be changed,

and then x-3 ==> x = 4.

so, loop will continue,

now, it will print 4 on the screen and then the line will be changed,

and then x-3 ==> x = 1.

so, loop will continue,

now, it will print 1 on the screen and then the line will be changed,

and then x-3 ==> x = -2

now loop will be terminated.

And so output will be -->

question : Take the recursive Java program Levenshtein.java and convert it to the equivalent C program. Tip: You have explicit permission to copy/paste the main method for this question, replacing instances of System.out.println with printf, where appropriate. You can get the assert function from assert.h. Try running the Java program on the CS macOS machines. You can compile and run the program following the instructions discussed in class. Assertions are disabled by default. You can enable assertions by running java...

Question 1 - Debugging Java Problem Description: Commonly attributed to Grace Hopper in the 1940s (when a moth found in a computer relay was fouling outputs), debugging is the practice of removing errors from code. It is a systematic procedure of examining the output, drawing a hypothesis for the cause of the error, then either implementing a correction or otherwise validating or falsifying the original error hypothesis. We are hunting and correcting errors in a controlled, systematic fashion. Most IDEs...
