PAT (Advanced Level) Practice 1002 A+B for Polynomials (25 分) 凌宸1642 题目描述: This time, you are supposed to find A+B where A and B are two polynomials. 译:这一次,你要找到 A + B ,其中 A , B 是两个多项式 Input Specification (输入说明): Each input file contains one test case…

With highways available, driving a car from Hangzhou to any other city is easy. But since the tank capacity of a car is limited, we have to find gas stations on the way from time to time. Different gas station may give different price. You are asked…
