Hi, question link- CodeChef: Practical coding for everyone this is my code- CodeChef: Practical coding for everyone why it is wrong which test case it is failing? i tried most of the test cases. like - 3 3 3 3 3 1 2 3 4 5 5 4 3 2 1 5 4 2 4 1
can anyone plz tell me.
input is a set of integers. So cases like 3 3 3 3, dont need to be taken care of, all integers will be unique. I can’t really comprehend your “java” solution but i don’t think u need to use divide and conquer for this question.
Yes, i used divide and conquer. I dont know why it is giving wrong answer.
use long for ans variable…because for n=10^5 inversions is 4.9*10^9 > Integer.MAX_VALUE
Thanks done!
