Description Farmer John has a balance for weighing the cows. He also has a set of N (1 <= N <= 1000) weights with known masses (all of which fit in 31 bits) for use on one side of the balance. He places a cow on one side of the balance and then adds
运算符:一.算术运算符:+ - * /% ——取余运算取余运算的应用场景:1.奇偶数的区分.2.把数变化到某个范围之内.——彩票生成.3.判断能否整除.——闰年.平年. int a = 10, b = 3; Console.WriteLine("10/3=" + (a / b)); Console.WriteLine("10%3=" + (a % b)); ++(自增运算) --(自减运算)——它只能对变量进行运算.int a = 5;a++; //7++; //错
