Problem Statement
There is dollars in a bank. Two bank operations are allowed: to withdraw dollars from the bank or to deposit dollars into the bank. These operations can be repeated as many times as necessary but only the money that was initially in the bank can be used. What is the largest amount of money that can be borrowed from the bank? How can this be done? (AK Tolpygo)
