10402: C.机器人 Description Dr. Kong 设计的机器人卡尔非常活泼,既能原地蹦,又能跳远.由于受软硬件设计所限,机器人卡尔只能定点跳远.若机器人站在(X,Y)位置,它可以原地蹦,但只可以在(X,Y),(X,-Y),(-X,Y),(-X,-Y),(Y,X),(Y,-X),(-Y,X),(-Y,-X)八个点跳来跳去. 现在,Dr. Kong想在机器人卡尔身上设计一个计数器,记录它蹦蹦跳跳的数字变化(S,T),即,路过的位置坐标值之和. 你能帮助Dr. Kong判断机器人能否…
欧几里德算法 欧几里德算法又称辗转相除法,用于计算两个整数a,b的最大公约数. 基本算法:设a=qb+r,其中a,b,q,r都是整数,则gcd(a,b)=gcd(b,r),即gcd(a,b)=gcd(b,a%b). 第一种证明: a可以表示成a = kb + r,则r = a mod b 假设d是a,b的一个公约数,则有 d|a, d|b,而r = a - kb,因此d|r 因此d是(b,a mod b)的公约数 假设d 是(b,a mod b)的公约数,则 d | b , d |r ,但是a…
