"""Write a function to find the three most common characters in the company's logo.
1. Define a function that takes a string as input.
2. Inside the function, count the frequency of each character and then find the three most common characters.
3. Return a list of tuples, where each tuple contains a character and its frequency.

Example
input:'google'
output:[('g', 2), ('o', 2), ('l', 1)] , three most common character

Input:facebook
Output:[('o', 2), ('f', 1), ('a', 1)]

Input:microsoft
Output:[('o', 2), ('m', 1), ('i', 1)]

Input:apple
Output:[('p', 2), ('a', 1), ('l', 1)]
