@Simran-Tuteja-2103059593355380 hey Simran your code is not working for this case.
1
8
1 34 3 98 9 76 45 4
your output is 989764543431
but the expected output is 998764543431.
I will recommend you to use the inbuilt sort function to sort the array with a custom comparator function.

#3

could you please explain what should be the comparator

#4

@Simran-Tuteja-2103059593355380
int myCompare(string X, string Y)
{
// first append Y at the end of X

// then append X at the end of Y


// Now see which of the two formed numbers is greater
return XY.compare(YX) > 0 ? 1: 0;

}
