Verified with

test/aoj/ALDS1_5_D.test.cpp

Code

#ifndef call_from_test
#include <bits/stdc++.h>
using namespace std;

#define call_from_test
#include "../datastructure/binaryindexedtree.cpp"
#undef call_from_test

#endif

//BEGIN CUT HERE

  for(T v:vs){
    assert(v<=n);
    res+=bit.query(v+1,n+1);
    bit.add(v,1);
  }
  return res;
}
