Write a function named remove_palindromes
that that removes all strings that are palindromes from a list of strings.
Your function accepts a list of strings as a parameter and modifies its contents, replacing every string in the list that is a palindrome with an empty string, ""
.
For example, if a list named phrases
stores the following element values:
a = ["Madam", "raceCAR", "", "hi", "A", "Abba", "banana", "dog God",
"STOP otto POTS", "Madame", "Python", "LevEL", "staTS"]
Then the call of remove_palindromes(phrases)
should change it to contain the following element values.
Notice that the palindromes from the list such as "Madam"
and "LevEL"
have been replaced by ""
.
["", "", "", "hi", "", "banana", "", "", "Madame", "Python", "", ""]
Constraints:
You are to modify the existing list in-place.
Do not create any other data structures such as temporary lists.
You may create as many strings as you like, and you may use as many simple variables as you like.
Note: You may want to go solve the string problem is_palindrome
first and use it as part of your solution to this problem.
