Hi, here's your problem today. This problem was recently asked by Uber:
Given a linked list of integers, remove all consecutive nodes that sum up to 0.
Example:
Input: 10 -> 5 -> -3 -> -3 -> 1 -> 4 -> -4
Output: 10
The consecutive nodes 5 -> -3 -> -3 -> 1 sums up to 0 so that sequence should be removed. 4 -> -4 also sums up to 0 too so that sequence should also be removed.
Here's a starting point:

Here's a starting point:
class Node:
def __init__(self, value, next=None):
self.value = value
self.next = next
def removeConsecutiveSumTo0(node):
# Fill this in.
node = Node(10)
node.next = Node(5)
node.next.next = Node(-3)
node.next.next.next = Node(-3)
node.next.next.next.next = Node(1)
node.next.next.next.next.next = Node(4)
node.next.next.next.next.next.next = Node(-4)
node = removeConsecutiveSumTo0(node)
while node:
print node.value,
node = node.next
# 10
