I sorted the input in lexicographical order and printed that ,but still i am getting WA. Does input contains number like 0988, etc. ?? Any hint what could be its reason? (not even a single tc is passing)
Form Biggest number - STL
@shivampandey9599 hey simple sorting will not work here if the given numbers are {54, 546, 548, 60}, the arrangement 6054854654 gives the largest value.Also 548 is greater than 60, but in output 60 comes before 548. As a second example, 98 is greater than 9, but 9 comes before 98 in output. So use this approach:
n the used sorting algorithm, instead of using the default comparison, write a comparison function myCompare() and use it to sort numbers.
Given two numbers X and Y, how should myCompare() decide which number to put first – we compare two numbers XY (Y appended at the end of X) and YX (X appended at the end of Y). If XY is larger, then X should come before Y in output, else Y should come before. For example, let X and Y be 542 and 60. To compare X and Y, we compare 54260 and 60542. Since 60542 is greater than 54260,
we put Y first.
