02_最长上升子串长度

一、测试程序： 

 1 /*
 2  *    最长上升子串长度
 3  *
 4  */

 6 #include 
 7 #include <string.h>
 8 
 9 #define MAX(a, b)    (a)>(b) ? (a):(b)
10 
11 int main()

17         int len = 0;
18         int max = 0;
19         int i = 0;
20 
21         len = strlen(str);
22         for (; i1; i++) {
23             if (str[i+1] > str[i])

30
