Problem #95

Write a function that takes an integer a and returns true 
if this ingeger is a cube of some integer number.
Note: you may assume the input is always valid.
Examples:
iscube(a: 1) == true
iscube(a: 2) == false
iscube(a: -1) == true
iscube(a: 64) == true
iscube(a: 0) == true
iscube(a: 180) == false

func iscube(a: Int) -> Bool { ...

XCTAssertTrue(iscube(a: 1) == true)
XCTAssertTrue(iscube(a: 2) == false)
XCTAssertTrue(iscube(a: -1) == true)
XCTAssertTrue(iscube(a: 64) == true)
XCTAssertTrue(iscube(a: 180) == false)
XCTAssertTrue(iscube(a: 1000) == true)
XCTAssertTrue(iscube(a: 0) == true)
XCTAssertTrue(iscube(a: 1729) == false)

Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes an integer a and returns true 
if this ingeger is a cube of some integer number.
Note: you may assume the input is always valid.
Examples:
iscube(a: 1) == true
iscube(a: 2) == false
iscube(a: -1) == true
iscube(a: 64) == true
iscube(a: 0) == true
iscube(a: 180) == false<end_of_turn>

func iscube(a: Int) -> Bool {
    let root = Int(sqrt(Double(a)))

}

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes an integer a and returns true 
if this ingeger is a cube of some integer number.
Note: you may assume the input is always valid.
Examples:
iscube(a: 1) == true
iscube(a: 2) == false
iscube(a: -1) == true
iscube(a: 64) == true
iscube(a: 0) == true
iscube(a: 180) == false

Answer:
```swift
func iscube(a: Int) -> Bool {
    let root = Int(sqrt(Double(a)))
    return a == root * root * root
}
```

 // Fatal error: Double value cannot be converted to Int because it is either infinite or NaN

iscube(a: 2) == false
iscube(a: -1) == true
iscube(a: 64) == true
iscube(a: 0) == true
iscube(a: 180) == false

Answer:
```swift
func iscube(a: Int) -> Bool {
    var x = Int(pow(Double(a), 1.0/3.0))
    return x*x*x == a
}
```

var x = Int(pow(Double(a), 1.0/3.0)) // variable 'x' was never mutated; consider changing to 'let' constant

 // Fatal error: Double value cannot be converted to Int because it is either infinite or NaN

func iscube(a: Int) -> Bool {
    let root = Int(pow(Double(a), 1.0/3.0))
    return Int(pow(Double(root), 3.0)) == a
}

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes an integer a and returns true 
if this ingeger is a cube of some integer number.
Note: you may assume the input is always valid.
Examples:
iscube(a: 1) == true
iscube(a: 2) == false
iscube(a: -1) == true
iscube(a: 64) == true
iscube(a: 0) == true
iscube(a: 180) == false

Answer:
```swift
func iscube(a: Int) -> Bool {
    let root = Int(pow(Double(a), 1.0/3.0))
    return Int(pow(Double(root), 3.0)) == a
}
```

if this ingeger is a cube of some integer number.
Note: you may assume the input is always valid.
Examples:
iscube(a: 1) == true
iscube(a: 2) == false
iscube(a: -1) == true
iscube(a: 64) == true
iscube(a: 0) == true
iscube(a: 180) == false
### Response:
```swift
func iscube(a: Int) -> Bool {
    let x = Int(round(pow(Double(a), (1.0/3.0))))
    return x*x*x == a
}
```

 // Fatal error: Double value cannot be converted to Int because it is either infinite or NaN

func iscube(a: Int) -> Bool {
    let cubeRoot = Int(pow(Double(a), (1.0 / 3.0)))
    return cubeRoot * cubeRoot * cubeRoot == a
}

Write a function that takes an integer a and returns true 
if this ingeger is a cube of some integer number.
Note: you may assume the input is always valid.
Examples:
iscube(a: 1) == true
iscube(a: 2) == false
iscube(a: -1) == true
iscube(a: 64) == true
iscube(a: 0) == true
iscube(a: 180) == false
### Response:
```swift
func iscube(a: Int) -> Bool {
    let root = Double(a).cubeRoot()
    return root == floor(root)
}

extension Double {
    func cubeRoot() -> Double {
        return pow(Double(self), 1.0/3.0)
    }
}
```

func iscube(a: Int) -> Bool {
    if a == 0 {
        return true

XCTAssertTrue(iscube(a: 1) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 2) == false) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: -1) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 64) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 180) == false) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 1000) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 0) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 1729) == false) // cannot find 'iscube' in scope

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes an integer a and returns true 
if this ingeger is a cube of some integer number.
Note: you may assume the input is always valid.
Examples:
iscube(a: 1) == true
iscube(a: 2) == false
iscube(a: -1) == true
iscube(a: 64) == true
iscube(a: 0) == true
iscube(a: 180) == false
### Response:
```swift
func iscube(a: Int) -> Bool {
    if a == 0 {
        return true

XCTAssertTrue(iscube(a: 1) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 2) == false) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: -1) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 64) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 180) == false) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 1000) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 0) == true) // cannot find 'iscube' in scope

XCTAssertTrue(iscube(a: 1729) == false) // cannot find 'iscube' in scope

```
Explanation:
The function takes an integer `a` as input and checks if it is a cube of some integer number.
If `a` is 0, it is a cube of 0, so the function returns `true`.
Otherwise, the function calculates the square root of `a` using the `sqrt` function from the `Math` module in Swift. If the result is equal to `a`, then `a` is a cube of some integer number, so the function returns `true`. Otherwise, the function returns `false`.

Note: The `sqrt` function returns a `Double` value, so the function must convert the result to an `Int` using the `Int` initializer.

Test Cases:
```swift
print(iscube(a: 1)) // true
print(iscube(a: 2)) // false
print(iscube(a: -1)) // true
print(iscube(a: 64)) // true
print(iscube(a: 0)) // true
print(iscube(a: 180)) // false
```
### Conclusion:
In this challenge, we have written a function in Swift that takes an integer `a` as input and returns `true` if `a` is a cube of some integer number. If `a` is 0, the function returns `true`. Otherwise, the function calculates the square root of `a` and checks if the result is equal to `a`. If the result is equal to `a`, then `a` is a cube of some integer number, so the function returns `true`. Otherwise, the function returns `false`.

Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes an integer a and returns true 
if this ingeger is a cube of some integer number.
Note: you may assume the input is always valid.
Examples:
iscube(a: 1) == true
iscube(a: 2) == false
iscube(a: -1) == true
iscube(a: 64) == true
iscube(a: 0) == true
iscube(a: 180) == false
### Response:
```swift
func iscube(a: Int) -> Bool {
    if a == 0 {
        return true
    }
    let root = sqrt(Double(a))
    return root == Int(root)
}
```

return root == Int(root) // binary operator '==' cannot be applied to operands of type 'Double' and 'Int'

func iscube(a: Int) -> Bool {
    if a == 0 {
        return true
    }
