DSA Coding Problems (2024)

Section titled “DSA Coding Problems (2024)”

Question 1: Longest Palindromic Substring

Section titled “Question 1: Longest Palindromic Substring”
Q1: Given a string s, return the longest palindromic substring in s.

Example:

Input: s = "babad"
Output: "bab" or "aba"

Solution (Java):

public String longestPalindrome(String s) {
    if (s == null || s.length() < 1) return "";
    int start = 0, end = 0;


    for (int i = 0; i < s.length(); i++) {
        int len1 = expandAroundCenter(s, i, i);
        int len2 = expandAroundCenter(s, i, i + 1);
        int len = Math.max(len1, len2);


        if (len > end - start) {
            start = i - (len - 1) / 2;
            end = i + len / 2;
        }
    }


    return s.substring(start, end + 1);
}


private int expandAroundCenter(String s, int left, int right) {
    while (left >= 0 && right < s.length() && s.charAt(left) == s.charAt(right)) {
        left--;
        right++;
    }
    return right - left - 1;
}
