๐Ÿ“˜ Minimum Insertions to Make a String Palindrome

๐Ÿ“ฐ Dev.to ยท Dolly Sharma

Learn to find the minimum insertions to make a string palindrome using Longest Palindromic Subsequence (LPS)

intermediate Published 22 Mar 2026
Action Steps
  1. Define the problem and identify the input string
  2. Initialize a 2D array to store the lengths of the longest palindromic subsequences
  3. Fill the 2D array using dynamic programming
  4. Calculate the minimum number of insertions required to make the string palindrome
  5. Implement the solution in a programming language like Python or Java
Who Needs to Know This

This benefits software engineers and developers who work with string manipulation algorithms, as it enhances their problem-solving skills and knowledge of dynamic programming.

Key Insight

๐Ÿ’ก The minimum number of insertions is equal to the difference between the length of the input string and the length of its Longest Palindromic Subsequence (LPS)
