Count Character Frequencies

EasyPython

Problem

Count the frequencies of chars in the char array.

Implement count_char_frequencies(char_array) to return a dictionary mapping each character to its number of occurrences. Matching is case-sensitive, and each array element contains exactly one character. Return an empty dictionary for an empty array.

Function signature: def count_char_frequencies(char_array): The output is a dictionary from characters to integer counts.

Constraints

0 <= len(char_array) <= 1000
Each element of char_array is a string containing exactly one character
Matching is case-sensitive

Function Signature

def count_char_frequencies(char_array):
