#K64412. Minimum Deletions to Palindrome
Minimum Deletions to Palindrome
Minimum Deletions to Palindrome
You are given a non-empty string s
. Your task is to determine the minimum number of deletions needed to transform s
into a palindrome.
A palindrome is a string that reads the same forwards and backwards. One effective way to solve this problem is to first compute the length of the longest palindromic subsequence (LPS) of s
. Then, the minimum number of deletions required is given by:
\(\text{minDeletions} = n - LPS\)
where \(n\) is the length of the string s
. Use dynamic programming to compute the LPS efficiently.
inputFormat
The input consists of a single line containing the string s
.
Constraints: \(1 \leq |s| \leq 1000\).
outputFormat
Output a single integer representing the minimum number of deletions required to convert the string into a palindrome.
