Problem Simple1

Problem Statement

The square length of a string is the square of the number of characters in the string. The square length of "hello" is 25, the square length of "a" is 1, and the square length of "apple sauce" is 121.

Given a string, write a function that returns the string's square length.

Definition

Class: SquareLength
Method: length
Parameters: String
Returns: int
Method signature (see below)

Prototype

public class SquareLength { public int length(String str) { // fill in code here } }

Constraints

The square length of the parameter s will be less than INT_MAX, you do not need to worry about integer overflow.

Examples

(quote for clarity, they're not part of the string)

```
  "hello"

Returns:  25
```
From above
```
    

  "apple sauce"

Returns: 121
```
```
   
  ""

Returns:0
```
The empty string has zero length.


  "dorothy the dinosaur"

Returns: 400
