Given a number n, return the number of positive odd numbers below n, EASY!

Examples (Input -> Output)
7 -> 3 (because odd numbers below 7 are [1, 3, 5])
15 -> 7 (because odd numbers below 15 are [1, 3, 5, 7, 9, 11, 13])

Write a simple regex to validate a username. Allowed characters are:

lowercase letters,
numbers,
underscore
Length should be between 4 and 16 characters (both included).

Write a function that accepts an integer n and a string s as parameters, and returns a string of s repeated exactly n times.

Examples (input -> output)
6, "I" -> "IIIIII"
5, "Hello" -> "HelloHelloHelloHelloHello"

You were camping with your friends far away from home, but when it's time to go back, you realize that your fuel is running out and the nearest pump is 50 miles away! You know that on average, your car runs on about 25 miles per gallon. There are 2 gallons left.

Considering these factors, write a function that tells you if it is possible to get to the pump or not.

Function should return true if it is possible and false if not.

Your task is to make two functions ( max and min, or maximum and minimum, etc., depending on the language ) that receive a list of integers as input, and return the largest and lowest number in that list, respectively.

Examples (Input -> Output)
* [4,6,2,1,9,63,-134,566] -> max = 566, min = -134
* [-52, 56, 30, 29, -54, 0, -110] -> min = -110, max = 56
* [42, 54, 65, 87, 0] -> min = 0, max = 87
* [5] -> min = 5, max = 5

You are given two sorted arrays that both only contain integers. Your task is to find a way to merge them into a single one, sorted in asc order. Complete the function mergeArrays(arr1, arr2), where arr1 and arr2 are the original sorted arrays.

You don't need to worry about validation, since arr1 and arr2 must be arrays with 0 or more Integers. If both arr1 and arr2 are empty, then just return an empty array.

Note: arr1 and arr2 may be sorted in different orders. Also arr1 and arr2 may have same integers. Remove duplicated in the returned result.

Examples (input -> output)
* [1, 2, 3, 4, 5], [6, 7, 8, 9, 10] -> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

* [1, 3, 5, 7, 9], [10, 8, 6, 4, 2] -> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

* [1, 3, 5, 7, 9, 11, 12], [1, 2, 3, 4, 5, 10, 12] -> [1, 2, 3, 4, 5, 7, 9, 10, 11, 12]

Create a method to see whether the string is ALL CAPS.

Examples (input -> output)

"c" -> False
"C" -> True
"hello I AM DONALD" -> False
"HELLO I AM DONALD" -> True
"ACSKLDFJSgSKLDFJSKLDFJ" -> False
"ACSKLDFJSGSKLDFJSKLDFJ" -> True

A string is said to be in ALL CAPS whenever it does not contain any lowercase letter so any string containing no letters at all is trivially considered to be in ALL CAPS.

Suzuki is a monk who climbs a large staircase to the monastery as part of a ritual. Some days he climbs more stairs than others depending on the number of students he must train in the morning. He is curious how many stairs might be climbed over the next 20 years and has spent a year marking down his daily progress.

The sum of all the stairs logged in a year will be used for estimating the number he might climb in 20.

20_year_estimate = one_year_total * 20

You will receive the following data structure representing the stairs Suzuki logged in a year. You will have all data for the entire year so regardless of how it is logged the problem should be simple to solve.

stairs = [sunday, monday, tuesday ,wednesday, thursday, friday, saturday]
Make sure your solution takes into account all of the nesting within the stairs array.

Each weekday in the stairs array is an array.

sunday = [6737, 7244, 5776, 9826, 7057, 9247, 5842, 5484, 6543, 5153, 6832, 8274, 7148, 6152, 5940, 8040, 9174, 7555, 7682, 5252, 8793, 8837, 7320, 8478, 6063, 5751, 9716, 5085, 7315, 7859, 6628, 5425, 6331, 7097, 6249, 8381, 5936, 8496, 6934, 8347, 7036, 6421, 6510, 5821, 8602, 5312, 7836, 8032, 9871, 5990, 6309, 7825]

Your function should return the 20 year estimate of the stairs climbed using the formula above.
