hello @laksh.rustagi12

the logic is if a and b are two numbers then u can combine them in two ways either ab or ba right?
which ever combination give us maxium we will consider that order.
so just apply same logic in ur comparator and sort using this comparator

bool cmp(string a,string b){
return a+b > b+a;
}
