Frequency of Characters

Asked in:
Accenture

Problem Description

Given a string A, find the frequency of all the characters in it.

Problem Constraints

1 <= |A| <= 10⁵
Ai = {Lowercase latin alphabets}

Input Format

Given a string A.

Output Format

Return an integer array of length 26.
Array should contain frequency of characters in increasing order of characters.

Example Input

Input 1:

A = "abcdefghijklmnopqrstuvwxyz"

Input 2:

A = "interviewbit"

Example Output

Output 1:

{1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1}

Output 2:

{0, 1, 0, 0, 2, 0, 0, 0, 3, 0, 0, 0, 0, 1, 0, 0, 0, 1, 0, 2, 0, 1, 1, 0, 0, 0}

Example Explanation

Explanation 1:

Every charcater is present once in the string.

Explanation 2:

'b' is at indices 10.
'e' is at indices 4, 8
'i' is at indices 1, 7, 11
'n' is at indices 2
'r' is at indices 5
't' is at indices 3, 12
'v' is at indices 6
'w' is at indices 9
Rest of the characters are not present in the string

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
