# Find the largest continuous sum | Python

Problem : Given an array of integers(positive and neg), Find the largest continuous sum . Solution : def large_cont_sum(arr): if len(arr) < 1 : return 0 max_sum = current_sum = arr[0] for num in arr[1:]: current_sum = max(num,current_sum+num) max_sum = max(current_sum,max_sum) print max_sum large_cont_sum([1,2,-1,3,4,10,10,-10,-1]) #29

# Linked List Nth to Last Node | Python

Problem : Function that takes a head node and an integer value n and then returns the nth to last node in the linked list.
