Answer 1

Alright try making this code:
A user will need to input a string and then it outputs the same string but they're randomly cased down or up for example:
INPUT: Hello World
OUTPUT: heLLO wOrLD

Answer 2

Write a code on finding the Kaprekar constant. You take any 4-digit number and put its digits in a descending order. You then subtract from it the combination in ascending order.
You do the same with the subtraction result until you reach a certain number, which, when transformed and performed the subtraction, shall not change anymore.

Example:
3529 -> start
9532 - 2359 = 7173
7731 - 1377 = 6354
...
