No need to explicitly print anything; assume that all necessary output operations have been handled.

Accepted Answer

Develop a function to remove all instances of a given character from a string.

Iterate through the string character by character and exclude the specified character while constructing the new string.
Use a StringBuilder or similar data structure for efficient string manipulation.
Handle edge cases such as empty string or character not found in the input string.
Ensure the function runs in O(N) time complexity where N is the length of the input string.
