Find Strings with Substring

Avito

Write a function findSubstring(substring, arr) that takes a string substring and an array of strings arr, and returns an array of strings that contain the substring substring.

- The substring must be found anywhere in the string.
- Character case matters (case-sensitive).
- If no string contains the substring, return an empty array.

Examples:

Input 1: "oo", ["food", "door", "moon"]

Output 1: ["food", "door", "moon"]

Input 2: "xyz", ["apple", "banana", "cherry"]

Output 2: []
