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 three integers x, y, z, the number of small to large output of these three please. 1 program analysis: we find a way to put the smallest number x, the first to compare x and y, if x>　y x and y values ​ ​ will be exchanged, and then use to compare x and z, if x >　z x and z values ​ ​ will be exchanged, so make the x minimum. .
