无意间看到，力扣存算法代码居然还得升级vip。。。好吧，我自己存吧
继续记录……
golang：
func removeDuplicates(nums []int) int {
if len(nums) <= 2 {
return len(nums)
}
insertIndex := 2
for i := 2; i < len(nums); i++ {
if nums[i] != nums[insertIndex - 2] {
nums[insertIndex] = nums[i]
insertIndex++
}
}
return insertIndex
}javascript:
/**
* @param {number[]} nums
* @return {number}
*/
var removeDuplicates = function(nums) {
if(nums.length <= 2) {
return nums.length
}
insertIndex = 2
for(let i = 2;i < nums.length; i++) {
if(nums[i] != nums[insertIndex -2]) {
nums[insertIndex] = nums[i]
insertIndex++
}
}
return insertIndex
};python:
class Solution(object):
def removeDuplicates(self, nums):
"""
:type nums: List[int]
:rtype: int
"""
if len(nums) <= 2:
return len(nums)
insert_index = 2
for i in range(2, len(nums)):
if nums[i] != nums[insert_index - 2 ]:
nums[insert_index] = nums[i]
insert_index += 1
return insert_index
