# 15.11 (Print the characters in a string reversely) Rewrite Exercise 15.9 using a helper
# function to pass the substring for the high index to the function. The helper
# function header is:
# def reverseDisplayHelper(s, high):
def reverseDisplay(value):
reverseDisplayHelper(value, len(value) - 1)
def reverseDisplayHelper(s, high):
if high < 0:
print()
else:
print(s[high], end='')
reverseDisplayHelper(s, high - 1)
val = input("Enter a string: ")
reverseDisplay(val)
