Form biggest number

sir is this the correct way to approach this problem

and sir what are the mistakes

@qudsiya no its not correct
let us suppose you have to arrange two numbers A and B to obtain the larger number. You will have to decide which number to put first – we compare two numbers AB ( B appended at the end of A) and BA (A appended at the end of B). If AB is larger, then A should come before B in output, else B should come before. You can append them as strings for comparison.
