Create a function that takes an array of positive integers as a parameter and continuously adds each item to the total sum, but only if the current item is larger than the previous item. The function should return the total sum of all the valid items in the array.
Additionally, the function should keep track of the in... | codefeedback | [

Given a list of integers, write a lambda function that filters the list based on a given predicate. The predicate should return True for numbers that are divisible by 3 and False for all other numbers. The lambda function should return a new list containing only the filtered numbers in ascending order.
