Provide a correct Python 3 solution for this coding contest problem.
Takahashi, who works at DISCO, is standing before an iron bar. The bar has N-1 notches, which divide the bar into N sections. The i-th section from the left has a length of A_i millimeters.
Takahashi wanted to choose a notch and cut the bar at that point into two parts with the same length. However, this may not be possible as is, so he will do the following operations some number of times before he does the cut:
* Choose one section and expand it, increasing its length by 1 millimeter. Doing this operation once costs 1 yen (the currency of Japan).
* Choose one section of length at least 2 millimeters and shrink it, decreasing its length by 1 millimeter. Doing this operation once costs 1 yen.
Find the minimum amount of money needed before cutting the bar into two parts with the same length.
Constraints
* 2 \leq N \leq 200000
* 1 \leq A_i \leq 2020202020
* All values in input are integers.

Find the maximum possible sum of utilities of purchased integers.
Constraints
* 1 \leq N \leq 10^5
* 0 \leq K < 2^{30}
* 0 \leq A_i < 2^{30}(1\leq i\leq N)
* 1 \leq B_i \leq 10^9(1\leq i\leq N)
* All input values are integers.
Inputs
Input is given from Standard Input in the following format:
N K
A_1 B_1
:
A_N B_N
Outputs
Print the maximum possible sum of utilities of purchased integers.

problem
Taro bought 10 books. Later, I tried to find out the price based on the receipt, but the receipt was dirty and I could not read the price of a book. We decided to calculate the price of the book from the total price of 10 books and the prices of the other 9 books.
Write a program that outputs the price of the book whose price could not be read. The prices of books are all positive integers. Also, there is no need to consider the consumption tax.
