You can initialize an empty min heap or a min heap with some elements:
import cube from '@gabrielrufino/cube'
const minHeap1 = new cube.MinHeap()
const minHeap2 = new cube.MinHeap({
inputs: [4, 2, 1, 3, 5],
})
Use the property .data
to access the elements in the min heap:
import cube from '@gabrielrufino/cube'
const minHeap = new cube.MinHeap({
inputs: [4, 2, 1, 3, 5],
})
console.log(minHeap.data) // [ 1, 3, 2, 4, 5 ]
Use the property .size
to get how many elements the min heap has:
import cube from '@gabrielrufino/cube'
const minHeap = new cube.MinHeap({
inputs: [4, 2, 1, 3, 5],
})
console.log(minHeap.size) // 5
Use the property .isEmpty
to find out if the min heap is empty:
import cube from '@gabrielrufino/cube'
const minHeap1 = new cube.MinHeap()
const minHeap2 = new cube.MinHeap({
inputs: [4, 2, 1, 3, 5],
})
console.log(minHeap1.isEmpty) // true
console.log(minHeap2.isEmpty) // false
Use the property .min
to get the minimum element in the min heap:
import cube from '@gabrielrufino/cube'
const minHeap = new cube.MinHeap({
inputs: [4, 2, 1, 3, 5],
})
console.log(minHeap.min) // 1
Use the method .insert()
to insert a new element in the min heap:
import cube from '@gabrielrufino/cube'
const minHeap = new cube.MinHeap({
inputs: [4, 2, 1, 3, 5],
})
minHeap.insert(6)
console.log(minHeap.data) // [ 1, 3, 2, 4, 5, 6 ]
Use the method .extract()
to extract the min value of the min heap:
import cube from '@gabrielrufino/cube'
const minHeap = new cube.MinHeap({
inputs: [4, 2, 1, 3, 5]
})
const min = minHeap.extract()
console.log(min) // 1
console.log(minHeap.data) // [ 2, 4, 3, 5 ]
