[抄题]: Given a m x n matrix, if an element is 0, set its entire row and column to 0. Do it in-place. Example 1: Input: [ [1,1,1], [1,0,1], [1,1,1] ] Output: [ [1,0,1], [0,0,0], [1,0,1] ] [暴力解法]: 时间分析: 空间分析: [优化后]: 时间分析: 空间分析: [奇葩输出条件]: [奇葩…
1.文件类型类似于这样: 不过数据量比这个要更大一点. 2.对应上述数据的运行结果: import matplotlib.pyplot as plt with open('test.txt') as fob: lines=fob.readlines() #去除掉每行最后一个换行符,就可以正确统计了,我也真不知道是为什么 for i in range(len(lines)): lines[i]=lines[i].rstrip() #在这里要创建一个长度的list进行统计 #但是这个地方的lines…
