Problem Statement:
The program takes a string and creates a dictionary with key as first character and value as the
count of letter in the string and also, sort the dictionary w.r.t the values of count in descending
order.

Pseudocode:
Start of build_dict function
   An empty dictionary is declared
   Start of for loop to traverse through the letters of the string
       If letter is not present as a key in the dictionary
           The letter is initialized as the key and assign 1 to it ( since initially the count would be 1)
       Else
         The value of the letter as key in the dictionary is increased by 1

End of build_dict function

Sort the dictionary and assign it back to the same dictionary variable
Start of print_dict function
    Iterate over all the items of the dictionary
        Print the key and value
End of print_dict function

Start of main function
    User must enter a large string and store it in a variable
    Call the build_dict function with string parameter and return the dictionary
    Print dictionary using print_dict function
End of main function

Hint:- You can also use sorted function to sort the dictionary with respect to the values
associated with keys in descending order.
Sample input:-
enter word: ksbrfkdjsbkerf
Sample Output:[('k', 3), ('s', 2), ('b', 2), ('r', 2), ('f', 2), ('d', 1), ('j', 1), ('e', 1)]
