cutCube.js

/*
Coding in function ```cutCube```. function accept 2 parameter: ```volume``` and ```n```. ```volume``` is the volume of a cube. If we cut the cube into ```n``` block. please determine whether the length of the cube is an integer. return true or false. 

For example: 

volume=27, it can be divided into 27 blocks, each small cube side length is 1
```
cutCube(27,27) should return true
```
volume=512, it can be divided into 8 blocks, each small cube side length is 4
```
cutCube(512,8) should return true
```
volume=512, it can be divided into 64 blocks, each small cube side length is 2
```
cutCube(512,64) should return true
```
If the side length of small cube is not a integer, should return false.
```
cutCube(256,8) should return false
cutCube(27,3) should return false
cutCube(123,456) should return false
```
If it can't be divided evenly into ```n``` small cubes, should return false too.
```
cutCube(50000,50) should return false
cutCube(256,4) should return false
```
The two examples above seems to meet our requirements, but please note: a cube is unable to evenly divided into 50 pieces or 4 pieces. Only cubic numbers(such as 8,27,64,125,216...) can be used to divide the cube evenly.

function cutCube(volume,n){
return !((Math.cbrt(n))%1)&&!(volume%n)&&!((Math.cbrt(volume))%1)
}
