# 15.14 (Occurrences of a specified character in a string) Rewrite Exercise 15.10 using a
# helper function to pass the substring of the high index to the function. The
# helper function header is:
# def countHelper(s, a, high):
def count(s, a):
return countHelper(s, a, len(s) - 1)
def countHelper(s, a, high):
result = 0
if high >= 0:
result = countHelper(s, a, high - 1) + (1 if s[high] == a else 0)
return result
s, a = input("Enter a string and a character to count: ").split()
print("Character", a, "repeated", count(s.lower(), a.lower()), "times")
