Actually it's 31536000 (not 31356000) and 12314555(not 1231455) as described in the problem. Let's say the input is ab2ac999 then you have ['a','b','2','c','9'] is the set of characters. We can map this set to another set : [3,1,5,6,0]. Which mean character 'a' represents for 3, 'b'->1, '2'->5 ..... then you have the number 313560000, after that you can choose whatever base for this number, here in the example, they choose 10.
if you choose the set [1,2,3,4,5] to map, and with base 6, you will have the second result.
