| # --description--
 | ||
| 
 | ||
| Given the positive integers, x, y, and z, are consecutive terms of an arithmetic progression, the least value of the positive integer, n, for which the equation, x2 − y2 − z2 = n, has exactly two solutions is n = 27:
 | ||
| 
 | ||
| 342 − 272 − 202 = 122 − 92 − 62 = 27
 | ||
| 
 | ||
| It turns out that n = 1155 is the least value which has exactly ten solutions.
 | ||
| 
 | ||
| How many values of n less than one million have exactly ten distinct solutions?
 | ||
| 
 | ||
| # --hints--
 | ||
| 
 | ||
| `euler135()` should return 4989.
 | ||
| 
 | ||
| ```js
 | ||
| assert.strictEqual(euler135(), 4989);
 | ||
| ```

| function euler135() {

|

|   return true;
 | ||

 | ||
| 
 | ||
| euler135();
