The program is for forming biggest number from an array of integers.
I am unable to unuderstand how string comparison is producing right and as far as I know string comparison works on ASCII values of individual characters.
Also if someone can suggest me a better approach of this question.
@vikanshu2016 Yes it does so on basis of individual characters , but does so in a loop, going from left to right .
In simple, all string comparison algorithm will follow the lexicographical order or dictionary order, which means it will check each character by character, if some mismatches, you can decide the result
