Please help! I am really struggling with this assignment and can't get any of my loops to work. Please show me how to recursively solve for the sum, call for factorials, and find the leftmost digit (I was trying to use the n-1 value or just printing the 0th number in the sequence.

Using switch and loops

1. intake user number n and solve for the sum of all values from 1 to n

2. intake user number and calculate the factorial (n!) of that number

3. intake user number and display the leftmost digit of that number
