Any hint to solve this problem ?

Many thanks !

Hi ,

I, actually, did all the methods which you mention, before I post the questions . what I tried to do is sorting array a with condition :
s[a ] < s[a[j]] (i<j) , not a <a[j] , (i<j) ....

if I declare a inner class like

class gg{
public:

class cmp{
public:
bool operator()(int a, int ...

Hi, i tried to sorting an array a, with a condition s[a ] <= s[a[j]] (i<j), s is given. Both a and s is contained inside a class. You can take a look at the sample source code.

#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
class gg{
public:

bool cmp( int a, int ...
