02_最长上升子串长度

一、测试程序： 

/*
 *    最长上升子串长度
 *
 */

#include <stdio.h>
#include <string.h>

#define MAX(a, b)    (a)>(b) ? (a):(b)

int main()
{
    unsigned char str[1024] = {0};

    while (~scanf("%s", str)) {
        int cnt = 1;
        int len = 0;
        int max = 0;
        int i = 0;

        len = strlen(str);
        for (; i<len-1; i++) {
            if (str[i+1] > str[i])
                cnt++;
            else
                cnt = 1;

            max = MAX(max, cnt);
        }

        printf("%d\n", max);
    }

    return 0;
}
