Coding questions (JavaScript) -> 1. Write a program to find if the two given integers have the same frequency of numbers. Like -> 11223 & 32121 (both have 2 - 1s, 2 - 2s, and 1 - 3). 2. Write a program to find if the first string contains the characters of the second string but the order should be the same. Like - (string, and sting --> So, order should be same - like S should appear before t in the first string)
