# --description--
|
|
|
|
In the hexadecimal number system numbers are represented using 16 different digits:
|
|
|
|
0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F
|
|
|
|
The hexadecimal number AF when written in the decimal number system equals 10x16+15=175.
|
|
|
|
In the 3-digit hexadecimal numbers 10A, 1A0, A10, and A01 the digits 0,1 and A are all present.
|
|
|
|
Like numbers written in base ten we write hexadecimal numbers without leading zeroes.
|
|
|
|
How many hexadecimal numbers containing at most sixteen hexadecimal digits exist with all of the digits 0,1, and A present at least once?
|
|
|
|
Give your answer as a hexadecimal number.
|
|
|
|
(A,B,C,D,E and F in upper case, without any leading or trailing code that marks the number as hexadecimal and without leading zeroes , e.g. 1A3F and not: 1a3f and not 0x1a3f and not $1A3F and not #1A3F and not 0000001A3F)

`euler162()` should return 3D58725572C62302.
|
|
|
|
```js
|
|
assert.strictEqual(euler162(), '3D58725572C62302');
|
|
```
|

## --seed-contents--
|
|
|
|
```js
|
|
function euler162() {
|
|
|
|
return true;
|
|
}
|
|
|
|
euler162();
|
