剑指offer之 二维数组查找

# -*- coding:UTF-8 -*-# 查找字符是否在一个二维数组中# 思路：从左下角开始查找#行数：m = len(array) -1#列数：n = len(array[0])-1class Solution:# arrary 二维数组def Find(self, targe, tarray):m = len(array)-1i = 0 while m >= 0 and i < len(array[0]):if array[m][i] > target:m -= 1elif array[m][i] < target:i += 1else:return Truereturn False
