Tested in MacOS

• Creates a file on your root: ~/.curlrc
• Adds -k inside of it.

This option allows curl to proceed and operate even for server connections otherwise considered insecure. The server connection is verified by making sure the server's certificate contains the right name and verifies successfully using the cert store.

See this online resource for further details: http://curl.haxx.se/docs/sslcerts.html

JavaScript

Sorted Squared Array

Write a function that takes in a non-empty array of integers that are sorted in ascending order and returns a new array of the same length with the squares of the original integers also sorted in ascending order.

Print the output like this: INPUT [1, 2, 3..] > OUTPUT [1, 4, 9..]

Sample Input

 array = [1, 2, 3, 5, 6, 8, 9]

Given an array of positive integers representing the values of coins in your possession, 
write a function that returns the minimum amount of change (the minimum sum of money) that you CANNOT create.

The given coins can have any positive integer value and aren't necessarily 
unique (i.e., you can have multiple coins of the same value).

Examples:
```
> {"coins": [5, 7, 1, 1, 2, 3, 22]} -> 20
> {"coins": [1, 1, 1, 1, 1]} -> 6
