Count Repeating Letters in a String | Dataford Interview Questions

In an LTIMindtree text-processing utility, implement a function that counts how many times a specified character appears in a string. The comparison must be case-sensitive, so "A" and "a" are different characters.

Formal Specification

Implement count_character(text, target):

Input: text, a string, and target, a string containing exactly one character.
Output: An integer representing the number of positions in text whose character equals target.
Count letters, digits, spaces, punctuation, and any other characters exactly as they appear.
Return 0 when the target does not occur or when text is empty.

Constraints

0 <= len(text) <= 10^5
target contains exactly one character
Matching is case-sensitive
text may contain spaces, punctuation, digits, or Unicode characters

Function Signature

def count_character(text, target):
