输入100个整数，求输出最小值，画流程图

一个简单的排序问题，流程图在这里不方便画，有兴趣的话可以去看看冒泡排序，对你应该有启发的

private int MinNum(int[] a, int startIndex)
{
if (startIndex == a.Length - 1 || a.Length == 1)
return a[startIndex];
else
{
return a[startIndex] < MinNum(a, startIndex + 1) ? a[startIndex] : MinNum(a, startIndex + 1);
}
}

private int MinNum(int[] a, int startIndex)
{
if (startIndex == a.Length - 1 || a.Length == 1)
return a[startIndex];
else
{
return a[startIndex] < MinNum(a, startIndex + 1) ? a[startIndex] : MinNum(a, startIndex + 1);
