26.删除排序数组中的重复项

func removeDuplicates(nums []int) int {
    for len(nums) == 0{
        return 0
    }
    left,right := 0,1
    for ;right<len(nums);right++{
        if nums[left] == nums[right]{
        continue
    }
    left++
    nums[left] = nums[right]
    }
    return left+1
}

1.两数之和

func twoSum(nums []int, target int) []int {
   for i:=0;i<len(nums)-1;i++{
       for j:=1;j<len(nums);j++{
           for (nums[i]+nums[j]) == target{
               return []int{i,j}
           }
       }
   }
   return nil
}

7.整数反转

func reverse(x int) int {
    var nums,newnums int
    a := x%10
    newnums = nums*10 + a
    nums = newnums
    x = x/10

    MaxInt32 := 1<<31-1
    MinInt32 := -1<<31
    if x>MaxInt32 || x<MinInt32{
        return 0
    }
    return nums
}
