leetcode -Remove Element

27. Remove Element

Given an array and a value, remove all instances of that value in place and return the new length. Do not allocate extra space for another array, 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.

解析：给一个队列和一个值value；要求去除队列中和value相等的元素。返回去除某值后的元素个数n。且不与value相等的元素要位于队列的前n位。

代码：

class Solution(object):
def removeElement(self, nums, val):
"""
:type nums: List[int]
:type val: int
:rtype: int
"""
c=0
for i in range(len(nums)):
if nums[i]==val:
continue
else:
nums[c]=nums[i]
c+=1
return c
