Test Case is working when I compile the code but not when submitting. Kindly assist me in understanding the logical flaw

hello @NimeshJohari02

consider this case->
1
2
2 21

here expected output is 221 but urs will give 212.

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

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

also print output for different test case in different line
