[LeetCode-Easy] Remove Duplicates from Sorted Array
Understand How To Solve This Problem Using Golang And Javascript.
Javascript
var removeDuplicates = function(nums) {
if (nums.length == 0){
return 0
}
let i = 0
for (let s = 1; s < nums.length; s++) {
if(nums[s] != nums[i]) {
i++
nums[i] = nums[s]
}
}
return i + 1
};
Golang
func removeDuplicates(nums []int) int {
if len(nums) == 0 {
return 0
}
c := 0
for i := 1; i < len(nums); i++ {
if nums[c] != nums[i] {
c++
nums[c] = nums[i]
}
}
return c + 1
}
c 設定為當前的位置
檢查當前的值 是否和下一位數一致
不一致就讓 c++
再讓加完後 c 的位置的值等於 loop 到的值
