Python解决打靶问题

动态语言永远是那么的飘逸。就似绝世神剑。高手用来心中有剑，低手则走火入魔。

from time import time
def shot(n, remain, his):
        """n goes 0-9"""
        if(remain < 0 or remain > (n + 1) * 10):
            return;
        if(n == 0):
            his[0] = remain;
            print his
            globals()["counter"] += 1
        else:
            for score in scores:
                his[n] = score;
                shot(n - 1, remain - score, his)
                
if __name__ == "__main__":
    scores = range(11)
    init = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
    counter = 0
    begin=time()
    shot(9, 90, init)
    end=time()
    print counter  
    print end-begin

 

不过貌似比较可惜的地方是，耗时27.2189998627，比起java来可慢的多咯
