Python: Find two indices making a given string unhappy
Python Programming Puzzles: Exercise-83 with Solution
A string is happy if every three consecutive characters are distinct. Write a Python program to find two indices associated with a given string being unhappy.
Input: Python Output: None Input: Unhappy Output: [4, 5] Input: Find Output: None Input: Street Output: [3, 4]

Sample Solution:
Python Code:
# License: https://bit.ly/3oLErEI
# Define a function named 'test' that takes a string 's' as input
def test(s):
# Iterate through the characters of the string up to the second-to-last character
for i in range(len(s) - 2):
# Check if consecutive characters are the same, return the indices if true
if s[i] == s[i + 1]:
return [i, i + 1]
# Check if characters with one character in between are the same, return the indices if true
if s[i] == s[i + 2]:
return [i, i + 2]
# Example 1
strs1 = "Python"
print("Original string:", strs1)
print("Find two indices making the string unhappy:")
print(test(strs1))
# Example 2
strs2 = "Unhappy"
print("\nOriginal string:", strs2)
print("Find two indices making the string unhappy:")
print(test(strs2))
# Example 3
strs3 = "Find"
print("\nOriginal string:", strs3)
print("Find two indices making the string unhappy:")
print(test(strs3))
# Example 4
strs4 = "Street"
print("\nOriginal string:", strs4)
print("Find two indices making the string unhappy:")
print(test(strs4))
Sample Output:
Original string: Python Find two indices making the said string unhappy! None Original string: Unhappy Find two indices making the said string unhappy! [4, 5] Original string: Find Find two indices making the said string unhappy! None Original string: Street Find two indices making the said string unhappy! [3, 4]
