# Challenge 193 Odd String ( Python )
# You are given a list of strings of same length, @s.
# Write a script to find the odd string in the given list. Use positional value of alphabet starting with 0, i.e. a = 0, b = 1, ... z = 25.
# Find the difference array for each string as shown in the example. Then pick the odd one out.
# ------------------------------------------------------------
# SAMPLE OUTPUT
# python .\OddString.py
# Input: @s = ['adc', 'wzy', 'abc']
# Output: abc
# Input: @s = ['aaa', 'bob', 'ccc', 'ddd']
# Output: bob
ss = [["adc", "wzy", "abc"],["aaa", "bob", "ccc", "ddd"]]
mylist = []
def StringValue(s) :
global mylist
v1 = ord(s[1]) - ord(s[0])
v2 = ord(s[2]) - ord(s[1])
saved = f"{v1},{v2}"
mylist.append(saved)
def main() :
for i in ss :
print(f"Input: @s = {i}")
global mylist
for x in range(len(i)) :
