Deletion of the sequence table

Take the data stored in the sequence table as an example of an integer type ~

• 按位序删除

bool ListDelete(SqList &L,int i,int &e){
    
	if(i<1||i>L.length)                  // i为位序
		return false;
	e=L.data[i-1];
	for(int j=i;j<=L.length-1;j++){
          //前移
		L.data[j-1]=L.data[j];
	}
	L.length--;
	return true;	
}

• 按下标删除

bool ListDelete(SqList &L,int i,int &e){
    
	if(i<0||i>L.length-1)                   // i为下标
		return false;
	e=L.data[i];
	for(int j=i+1;j<=L.length-1;j++){
           //前移
		L.data[j-1]=L.data[j];
	}
	L.length--;
	return true;	
}
