Homework

Multiplication Table

Write a program that prints multiplication table.

Expected output:

1	2	3	4	5	6	7	8	9	
2	4	6	8	10	12	14	16	18	
3	6	9	12	15	18	21	24	27	
4	8	12	16	20	24	28	32	36	
5	10	15	20	25	30	35	40	45	
6	12	18	24	30	36	42	48	54	
7	14	21	28	35	42	49	56	63	
8	16	24	32	40	48	56	64	72	
9	18	27	36	45	54	63	72	81

Power

Calculating power is one of the base operations in mathematics.

We can calculate a power operation with a single loop, with multiply the number exponent times.

For example 2^4 = (2 * 2 * 2 *2 ) is just multiplying 2, 4 times.

Make a program that calculates the given power of given base number.

Example input/output:

Enter a base number: 5
Enter an exponent: 4
5 ^ 4 = 625

Palindrome Numbers

Lets make a good example with working a number in a different way.

An palindrome number is a number that the reverse of that number is equal to the original number.

So we need to reverse a number and check if it is equal to its reverse.

We can make it with a loop, and every step of loop, we can take the last digit of original number and add it to reversed numbers last digit.

Hint: We can use "remainder = n % 10" expression for take the last digit (Not hint for how to add it to reversed number)
