URL Shortener

URL Shortener

How this works

When one object is saved in database, this generates an id (unique identification). This id will be used to convert in base 62. I used that approach to avoid conflict in short url generated; This way the short url generated will never be conflicted with another

Alghoritm

This alghoritm works converting numbers from base 10 to base 62. Base 10 are digits [0-9], and base 62 are digits [0-9][a-z][A-Z].

This meant, that, a number in base 10 with four digits would be tha same as number in base 62 with 2 digits.

How base 62 works

while(number>0){
    remainder=number%62;
    number=number/62;
}
