return max_sum

Here are some TCS coding questions from 2021, along with a useful piece of code for each:

# Create a sample linked list: 1 -> 2 -> 3 -> 4 -> 5 head = Node(1) head.next = Node(2) head.next.next = Node(3) head.next.next.next = Node(4) head.next.next.next.next = Node(5) Tcs Coding Questions 2021

while fast and fast.next: slow = slow.next fast = fast.next.next

Given an array of integers, find the maximum sum of a subarray. return max_sum Here are some TCS coding questions

print(is_palindrome("madam")) # Output: True

for num in arr: current_sum = max(num, current_sum + num) max_sum = max(max_sum, current_sum) current_sum + num) max_sum = max(max_sum

def max_subarray_sum(arr): max_sum = float('-inf') current_sum = 0

Example: Input - 1 -> 2 -> 3 -> 4 -> 5, Output - 3

def first_non_repeating_char(s): char_count = {} for char in s: if char in char_count: char_count[char] += 1 else: char_count[char] = 1
