Task 1: Counter Integers

Submitted by: Mohammad Sajid Anwar

You are given a string containing only lower case English letters and digits.

Write a script to replace every non-digit character with a space and then return all the distinct integers left.

Example 1

Input: $str = "the1weekly2challenge2"
Output: 1, 2

2 is appeared twice, so we count it one only.

Example 2

Input: $str = "go21od1lu5c7k"
Output: 21, 1, 5, 7

Example 3

Input: $str = "4p3e2r1l"
Output: 4, 3, 2, 1

Task 2: Nice String

Submitted by: Mohammad Sajid Anwar

You are given a string made up of lower and upper case English letters only.

Write a script to return the longest substring of the give string which is nice. A string is nice if, for every letter of the alphabet that the string contains, it appears both in uppercase and lowercase.

Example 1

Input: $str = "YaaAho"
Output: "aaA"

Example 2

Input: $str = "cC"
Output: "cC"

Example 3

Input: $str = "A"
Output: ""

No nice string found.
