class Solution { public int removeElement(int[] nums, int val) { int i=0,j=nums.length-1;//i-左指针;j-右指针 while (i<=j){ if(nums[i]==val){ nums[i]=nums[j];//得到索引j的值,无需把索引j的值改为索引i的值 j--; }else i++; } return j+1; } } Python3: 代码语言:...
Thepop()method is another way to remove an element from a list in Python. By default,pop()removes and returns the last element from the list. However, we can also specify the index of the element to be removed. So, here we will use the index number of the first element to remove i...
class Solution: def removeElement(self, nums: List[int], val: int) -> int: # l 表示不等于 val 的数字个数,也是下一个可以放入数字的下标,初始化为 0 l: int = 0 # 遍历剩余所有的数字 for r in range(len(nums)): # 如果当前数字不等于 val ,则 nums[r] 不需要移除,放入 l 处 if num...

1python list可以使用索引的特性,从后往前遍历。 2按照list的常规做法,从开头每次验证下一个节点是否与val相同, 最后验证头结点。 3使用python list.remove()函数,删除所有的val。 classSolution:defremoveElement(self, nums, val):""" :type nums: List[int] ...
def removeElement(self, nums: List[int], val: int) -> int: i=0 j=len(nums)-1 while i<=j: if(nums[i]==val): nums[i]=nums[j] j-=1 else:i+=1 return j+1 总结: 这道题本身很简单,只要搞清思路,一起都会变得明了。
