[英]How can we write a function List multiPop(int k) that pops k elements from the stack or until the stack is empty?
I am trying to write a method that pops k elements from the stack. 我正在尝试编写一种从堆栈中弹出k个元素的方法。 Any help would be appreciated.
任何帮助,将不胜感激。
This is what I have tried:
public void multipop(int k) {
List l = nil();
while (true) {
for(int i =0; i < k; i++) {
}
Translate the following concept in to Java: 将以下概念转换为Java:
create a list to store the popped members in.
while (the stack is not empty and we have to pop more elements) {
add a popped member from the stack to the list
}
return the list.
Done 完成
list multipop(int k, list stack){
int increment = 0;
while(stack.next() != null && k < increment){
stack.pop();
increment++;
}
}
return stack;
I'm sorting assuming you have the methods .next() and .pop() already created. 我在假设您已经创建了.next()和.pop()方法的情况下进行排序。
