K Palindrome
A string is a k-palindrome if it can be transformed into a palindrome by removing any amount of characters from 0
to k
. Your task is to determine whether the given string s
is a k-palindrome.
Example
For
s = "abrarbra"
andk = 1
, the output should bekpalindrome(s, k) = true
.You can remove one letter,
'r'
, to obtain the string"abrarba"
, which is a palindrome.For
s = "adbcdbacdb"
andk = 2
, the output should bekpalindrome(s, k) = false
.
