For eg. if we have two strings 2 and 10, 10 will come first if we order lexicographically.
The very trivial sol will be to repeat a character n number of time.
eg. 2 can be encoded as aa
10 as aaaaaaaaaa
This way the lex order is same as the numeric one.
But, is there a more elegant way to do this?
When converting the numbers to strings make sure that all the strings have the same length, by appending 0s in the front if necessary. So 2 and 10 would be encoded as “02” and “10”.
