2 ways to delete an element from a slice yourbasic.org/golang Fast version (changes order) a := []string{"A","B","C","D","E"} i :=2// Remove the element at index i from a.a[i] = a[len(a)-1]// Copy last element to index i.a[len(a)-1] =""// Erase last elem...
i := 2 // Remove the element at index i from a. copy(a[i:], a[i+1:]) // Shift a[i+1:] left one index. a[len(a)-1] = "" // Erase last element (write zero value). a = a[:len(a)-1] // Truncate slice. fmt.Println(a) // [A B D E] 1. 2. 3. 4. 5. ...
//删除切片元素remove element at index index:=5; ss=append(ss[:index],ss[index+1:]...) print("after delete",ss) //在切片中间插入元素insert element at index; //注意:保存后部剩余元素,必须新建一个临时切片 rear:=append([]string{},ss[index:]...) ss=append(ss[0:index],"inserted") ...
print("after append",ss) //删除切片元素remove element at index index:=5; ss=append(ss[:index],ss[index+1:]...) print("after delete",ss) //在切片中间插入元素insert element at index; //注意:保存后部剩余元素,必须新建一个临时切片 rear:=append([]string{},ss[index:]...) ss=append(...
// DeleteSliceE deletes the specified index element from the slice with error. // Note that the original slice will not be modified. func DeleteSliceE(slice interface{}, indexes ...int) (interface{}, error) { // check params v := reflect.ValueOf(slice) if v.Kind() != reflect.Sli...
delete(m, key) } 1. 2. 3. 当然,数组和切片元素也可以用传统的for循环来遍历。 for i := 0; i < len(anArrayOrSlice); i++ { element := anArrayOrSlice[i] // ... } 1. 2. 3. 4. 对一个for-range循环代码块 ...
s=append(s,0/* use the zero value of the element type */)copy(s[i+1:],s[i:])s[i]=x 插入Slice a=append(a[:i],append(b,a[i:]...)...) 增加元素 a=append(a,x) 取出最后一个元素 x,a=a[len(a)-1],a[:len(a)-1] ...

delete(t.keyToETask, taskElement.key) e = next } } 在circularIncr 方法中,呼应了环状数组的逻辑处理方式: // 每次 tick 后需要推进 curSlot 指针的位置,slots 在逻辑意义上是环状数组,所以在到达尾部时需要从新回到头部 func (t *TimeWheel) circularIncr() { ...
