Define a function that can receive three numbers, and implement the sorted output of three numbers in the function body → (declaration and call of the function that returns the value in javascript)

Analysis of "bit operator" Knowledge:

4. Bit operators
Tags: >> << & | ^
&: Bitwise AND, determine parity; do bitwise AND between any number and 1, if the result is 1, it is an odd number; if the result is 0, it is an even number
|: Bitwise OR, for Decimal rounding; any decimal is bitwise ORed with 0, and if it is saved, the integer part is taken
^: Bitwise XOR, used to exchange two numbers
a = a^b; b = b^a; a = a^b;
Abbreviation: a^=b; b^=a; a^=b;

定义一个可以接收三个数字的函数，函数体内实现三个数字的排序输出 
-->
	<script>
		function sortNum(a,b,c){
	//如果将最小的数字赋值给a,将最大的数字赋值给c
	//1.比较a与b的大小关系，如果a>b的话，则交换两个数字，则a中存放的就是 a和b 的最小值。
			a>b && (a^=b,b^=a,a^=b);
	//2.比较b与c的大小关系，如果b>c的话，则交换两个数字，则b中存放的就是 b和c 的最小值;则c中存放的是3个数字中的最大值。
			b>c && (b^=c,c^=b,b^=c);
	//3.最后在比较a与b中的（两个最小值的大小）大小关系，如果a>b的话，则交换两个数字，则a中存放的就是 a和b 的最小值。
			a>b && (a^=b,b^=a,a^=b);
			console.log(a,b,c);
		}
	</script>
	<button onclick="sortNum(52,36,98)">三个数字的排序</button>
 </body>
