方法/步骤 1 首先在PyCharm软件中，打开一个Python项目。2 在Python项目中，新建并打开一个空白的python文件（比如：test.py）。3 在python文件编辑区中，输入：“from array import *”，导入 array 模块内容。4 插入语句：“arr = array('u', 'Apple')
So I want to filter out from the above array of strings the following array b = ['ab','2'] I want to remove strings containing 'ab' from that list along with other strings in the array so that I get the following: a = ['blah', 'tete', 'head'] 1. 2. 3. 4. 5. 6. 更...

Given input arraynums=[3,2,2,3],val=3 Your function should return length = 2, with the first two elements ofnumsbeing 2. 给定一个数组和一个数值val,将数组中数值等于val的数去除,返回新数组的长度。不能申请额外空间,超过新数组长度部分忽略。
you must do this in place with constant memory. The order of elements can be changed. It doesn't matter what you leave beyond the new length.Example:Given input array nums = [3,2,2,3], val = 3 Your function should return length = 2, with the first two elements of nums being 2....
