Answer 1

def replace_the_last_occurrence_of_a_character_in_a_string(s, char_to_replace, replacement_char):
    pos = s.rfind(char_to_replace)

    if pos != -1:
        s = s[:pos] + replacement_char + s[pos + 1:]
    
    return s

s = "c++ c python c++ java c++ php"
char_to_replace = 'c'
replacement_char = 'W'

s = replace_the_last_occurrence_of_a_character_in_a_string(s, char_to_replace, replacement_char)
    
print(s)
