Regarding the use of practice problems

i am not able to understand the practice problem pattern ,how to solve it?

In this problem you need to take in a list as an input , it can be of any size.

When it comes to the output , you will have to maintain a variable (let’s call it sum ) , which will be initially equal to the first element of the list (list[0]).
You need to start a loop to iterate over all the elements of the list to print them and also add the list element which we just printed to the variable sum.
Note that as soon as the variable sum becomes negative we will stop our loop ( you can use ‘break’ for the same ).
