【蓝桥杯】递增序列 python

题目描述

本题为填空题,只需要算出结果后,在代码中使用输出语句将所填结果输出即可。

对于一个字母矩阵,我们称矩阵中的一个递增序列是指在矩阵中找到两个字母,它们在同一行,同一列,或者在同一 4545 度的斜线上,这两个字母从左向右看、或者从上向下看是递增的。

例如,如下矩阵中

LANN
QIAO

有LN、LN、AN、AN、IO、AO、LQ、AI、NO、NO、AQ、IN、ANLN、LN、AN、AN、IO、AO、LQ、AI、NO、NO、AQ、IN、AN 等 1313 个 递增序列。注意当两个字母是从左下到右上排列时,从左向右看和从上向下看 是不同的顺序。

对于下面的 3030 行 5050 列的矩阵,请问总共有多少个递增序列?

思路分析:

首先我们应该明白这一题的输入方式:

多行字符串输入,要用三引号,之后要通过分析例子来完全理解题,他这题的意思是首先条件,在同一行,或者同一列,或者是同一对角线,重点来了,他要“左向右看、或者从上向下”是递增的,什么意思?

就是可以是右上(从左往右),也可以是右下(从左往右),也可以是左下(从上到下)这几个方向递增。
