Direct Answer: What are the primary topics in TCS Digital?
TCS Digital coding rounds primarily focus on Arrays, Strings, Dynamic Programming, and Graph traversal. Candidates are tested on 2 coding problems: one medium (30 marks) and one hard (50 marks) within 60 minutes.
Question 1: Longest Palindromic Substring
Given a string s, return the longest palindromic substring in s.
def longestPalindrome(s: str) -> str:
res = ""
for i in range(len(s)):
# Odd length
l, r = i, i
while l >= 0 and r < len(s) and s[l] == s[r]:
if (r - l + 1) > len(res):
res = s[l:r+1]
l -= 1
r += 1
return res
