Consider the following Python code snippet:
def longest_palindrome(s):
    n = len(s)
    dp = [[False] * n for _ in range(n)]
    longest_length = 0
    start_index = 0
    for i in range(n):
        dp[i][i] = True
        longest_length = 1
    for length in range(2, n + 1):
        for i in range(n - length + 1):
            j = i + length - 1
            if s[i] == s[j]:
                if length == 2 or dp[i + 1][j - 1]:
                    dp[i][j] = True
                    longest_length = length
                    start_index = i
    return s[start_index: start_index + longest_length]
string = "babad"
print(longest_palindrome(string))
What is the output of the above code?
  • a)
    "bab"
  • b)
    "aba"
  • c)
    "bad"
  • d)
    "ad"
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Consider the following Python code snippet:def longest_palindrome(s): ...
The given code implements the dynamic programming approach to find the longest palindromic substring in a given string. The longest palindromic substring in the string "babad" is "aba".
