我确定应该有更有创意的方法来解决这个问题......有兴趣吗?
问:根据以下代码,确定“a”的可能值范围:
x = random_int(1,6)
y = random_int(1,6)
z = random_int(1,6)
a = x + y + z
我的回答:
var x, y, z, a;
var range = [];
for (var i = 0; i < 1000; i++) {
x = Math.floor(Math.random() * 6) + 1;
y = Math.floor(Math.random() * 6) + 1;
z = Math.floor(Math.random() * 6) + 1;
a = x + y + z;
range.push(a);
}
var min = Math.min.apply(null, range),
max = Math.max.apply(null, range);
document.write("The range is between " + min + " and " + max);

答案 0 :(得分:0)
这是所有代码:
document.write("The range is between 3 and 18");
因为最小值是所有randoms为1所以它将是
x = min(random_int(1,6)) = 1
y = min(random_int(1,6)) = 1
z = min(random_int(1,6)) = 1
所以
a = 1 + 1 + 1 = 3
,最大值将是这样的:
x = max(random_int(1,6)) = 6
y = max(random_int(1,6)) = 6
z = max(random_int(1,6)) = 6
所以
a = 6 + 6 + 6 = 18
