4. Given the nested while loop below, what will be the value of treasuresFound after the loop finishes if totalFloors is 2 and
totalRooms is 3?
int totalFloors = 2;
int totalRooms = 3;
int floor = 1;
int treasuresFound = 0;
while (floor <= totalFloors) {
int room = 1;
while (room <= totalRooms) {
treasuresFound++;
room++;
}
floor++;
}
System.out.println("Total treasures found: " + treasuresFound);
a. 2 b. 3

5. Each stall has 2 participants, and each participant presents 3 projects. How many times will the innermost loop execute in total?
for (int stall = 1; stall <= 3; stall++) {
int participant = 1;
while (participant <= 2) {
int project = 1;
do {
System.out.println("Stall " + stall + ", Participant " + participant + ",
Project " + project);
project++;
} while (project <= 3);
participant++;
}
}
a. 3 b. 6
c. 9 d. 18
B. Answer the following questions:
1. Write a program to input 10 numbers and print all the neon numbers.
2. Write a program to input a number and print whether the number is a Magic Number or not. A Magic number is a number
whose eventual sum of the digits of the number is equal to 1.
For example, n = 28 = 2 + 8 = 10 = 1+ 0 = 1
3. Write a program to print all the palindromic numbers between m and n (m<n). A palindromic number is a number whose reverse
of the digits is equal to the number.
For example, 121, 454, 66 etc.
4. Write a program to “n” numbers and print the sum of all the Armstrong numbers.
5. Write a program two numbers and print the whether it is a twin prime number or not. For example, say, 17,19 are twin primes
as the difference is 2 and both are prime numbers.
