### sdbmHashAlgorithm
This algorithm is a simple hash-algorithm that hashes it input string `s` into a whole number.
Use `split('')` and `Array.reduce()` to create a hash of the input string, utilizing bit shifting.
``` js
const sdbm = str => {
let arr = str.split('');
return arr.reduce((hashCode, currentVal) =>
hashCode = currentVal.charCodeAt(0) + (hashCode << 6) + (hashCode << 16) - hashCode
,0)
}
// console.log(sdbm("name")) // -3521204949
// console.log(sdbm("age")) // 808122783
```
