Given an array of integers, find the maximum sum of a subarray.
# 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) Output - 6 print(max_subarray_sum([-2
print(find_middle_element(head)) # Output: 3
return None
Example: Input - "aabbc", Output - "c"
return slow.data
def count_pairs_with_sum(arr, target_sum): count = 0 seen = set()
print(count_pairs_with_sum([1, 2, 3, 4, 5], 7)) # Output: 2 target sum - 7
Example: Input - "madam", Output - True
