找到数组中的最小值 [英] Find the lowest value in an array
问题描述
您好，
我有一个包含4个值的数组（它们包含随机数）。我想
喜欢找到最低价值（如果有领带我想找到一个
领带。）然后删除该值。我是Programming and C＃的新手。
感谢您提供的任何帮助

如果它总是4个元素则可能：
minval = Math.Min（Math.Min（a [0 ]，a [1]），Math.Min（a [2]，a [3]））;

过程之后，你应该有一个低值，一个只有三个元素的数组？ Lilith和Arne回答了排序问题。

Lilith和Arne回答了排序问题。
是的，但是排序是破坏性的，并且是一种非常低效的方式来找到
中最低的四个数字。由于删除的要求已经明确规定，
我将在这里忽略它。为了找到最低值，我绝对不会使用Sort或Math.Min或Max。
。为了最大限度地提高效率，可以使用以下内容：
int a = x [0];
int b = x [1];
int c = x [2];
int d = x [3];
//有效地a = Math.Min（a，b）
if（b< a）
{
a = b;
}
//有效地a = Math.Min（c，d）
if（d< ; c）
{
c = d;
}
//有效地数学 .Min（a，c）其中总的来说是Math.Min（a，
b，c，d）
返回（a< c）？ a：c;

Hello,
I have an array that holds 4 values ( they contain random numbers). I would
like to find the lowest value (if there is a tie i would like to find one of
the tie.) then remove that value. I am new to Programming and C#.
Thanks for any help you can provide

minval = Math.Min(Math.Min(a[0], a[1]), Math.Min(a[2], a[3]));

When you say "...then remove that value.", do you mean that after the
process, you should have a low value, and an array with only three elements?
Lilith and Arne answered the sorting issue.

Lilith and Arne answered the sorting issue.Yeah, but sorting is destructive and a very inefficient way to find the
lowest of four numbers. Since the ''remove'' requirement was well specified,
I''m going to ignore it here. To find the lowest value, I definitely
wouldn''t use a Sort or Math.Min or Max. To maximize efficiency, something
along the lines of:
int a = x[0];
int b = x[1];
int c = x[2];
int d = x[3];
// Effectively "a = Math.Min (a, b)"
if (b < a)
{
a = b;
}
// Effectively "a = Math.Min (c, d)"
if (d < c)
{
c = d;
}
// Effectively "Math.Min (a, c)" which in summary is really "Math.Min (a,
b, c, d)"
return (a < c) ? a : c;
