输入三个整数x,y,z，请把这三个数由小到大输出。 1.程序分析：我们想办法把最小的数放到x上，先将x与y进行比较，如果x>y则将x与y的值进行交换，然后再用x与z进行比较，如果x>z则将x与z的值进行交换，这样能使x最小。-Enter the three integers x, y, z, please these three the number of small to large output. 1. Program analysis: We think of a way to put x number of the smallest, the first comparison of x and y, if x> y will be the value of x and y exchange and then to compare x and z, if x > z will be x and z values of the exchange, which will enable x minimum.
