Character FrequencyGiven a string as input . Print the frequncy of each character in the string in alphabetical order of charactersConstraints:Input format :s1 -> string as input Output format :List of all characters along with its frequency in string Example:Input 1:googleOutput 1:['e', 1] ['g', 2] ['l', 1] ['o', 2]Input 2:PythonOutput 2:['P', 1] ['h', 1] ['n', 1] ['o', 1] ['t', 1] ['y', 1]

Here is a step-by-step solution in Python:

1. First, we need to define a function that takes a string as input.

def char_frequency(str1):

2. Then, we need to create a dictionary to store the frequency of each character.

    dict = {}

3. Next, we iterate over each character in the string. If the character is already in the dictionary, we increment its count. If it's not, we add it to the dictionary with a count of 1.

    for n in str1:
        keys = dict.keys()
        if n in keys:
            dict[n] += 1
        else:
            dict[n] = 1

4. Finally, we return the dictionary sorted by keys (characters) in alphabetical order.

    return sorted(dict.items())

5. Now, we can call the function with a string to get the frequency of each character.

print(char_frequency('google'))
print(char_frequency('Python'))

This will output:

[('e', 1), ('g', 2), ('l', 1), ('o', 2)]
[('P', 1), ('h', 1), ('n', 1), ('o', 1), ('t', 1), ('y', 1)]

This means that in the string 'google', 'e' appears 1 time, 'g' appears 2 times, 'l' appears 1 time, and 'o' appears 2 times. Similarly, you can interpret the output for 'Python'.
