Cube - Stack
You can initialize an empty stack or a stack with some elements:
import cube from '@gabrielrufino/cube'
const stack1 = new cube.Stack()
const stack2 = new cube.Stack(1, 2, 3, 4)
Use the property .data
to access the elements in the stack:
import cube from '@gabrielrufino/cube'
const stack = new cube.Stack(1, 2, 3, 4)
console.log(stack.data) // [ 1, 2, 3, 4 ]
Use the property .size
to get how many elements the stack has:
import cube from '@gabrielrufino/cube'
const stack = new cube.Stack(1, 2, 3, 4)
console.log(stack.size) // 4
Use the method .push()
to insert a new element in the top of the stack:
import cube from '@gabrielrufino/cube'
const stack = new cube.Stack(1, 2, 3)
stack.push(4)
console.log(stack.data) // [ 1, 2, 3, 4 ]
Use the method .pop()
to get and remove the element in the top of the stack:
import cube from '@gabrielrufino/cube'
const stack = new cube.Stack(1, 2, 3, 4)
const element = stack.pop()
console.log(stack.data) // [ 1, 2, 3 ]
console.log(element) // 4
Use the method .peek()
to get the element in the top of the stack without remove:
import cube from '@gabrielrufino/cube'
const stack = new cube.Stack(1, 2, 3, 4)
const element = stack.peek()
console.log(stack.data) // [ 1, 2, 3, 4 ]
console.log(element) // 4
Use the method .clear()
to remove all elements from stack:
import cube from '@gabrielrufino/cube'
const stack = new cube.Stack(1, 2, 3, 4)
stack.clear()
console.log(stack.data) // []
Use the property .isEmpty
to find out if the stack is empty:
import cube from '@gabrielrufino/cube'
const stack1 = new cube.Stack()
const stack2 = new cube.Stack(1, 2, 3, 4)
console.log(stack1.isEmpty) // true
console.log(stack2.isEmpty) // false
