# Lab #5¶

## Before Kattis¶

**1**

Write a *function* called `count_to_n_w(n)`

to print a count from 0 to `n-1`

. This function should use a *while* loop.

**2**

Write a function called `add_one_n_times_w(a, n)`

that will add **one** to a number `a`

a total of `n`

times. In the end, have this function `return`

the value. This function **must** use a `while`

loop. It should work such that:

```
>>> ans = add_one_n_times(7, 5)
>>> print(ans)
12
```

**3**

Write a *function* called `count_to_n_f(n)`

to print a count from 0 to `n-1`

. This function should use a *for* loop. **Hint:** check out range.

**4**

Write another function called `add_one_n_times_f(a, n)`

that will add **one** to a number `a`

a total of `n`

times, but this time with a `for`

loop.

## Kattis Problems¶

Grab a scrap piece of paper to start scratching your ideas down on paper. The problems are getting tricky enough where this really is becoming a requirement.
