can anyone please help me out.
#include<bits/stdc++.h>
using namespace std;
int main()
{
int t;
cin>>t;
while(tā)
{
int a[6],i,m=INT_MAX,j,z=0;
for(i=0;i<6;i++) cin >> a[i];
for(i=0;i<3;i++)
if(a[i]<m) {m=a[i]; j=i;}
swap(a[0],a[j]); swap(a[3],a[j+3]);
if(a[1]>a[2])
{swap(a[1],a[2]); swap(a[4],a[5]);}
for(i=1;i<3;i++)
{
if(a[i]==a[i-1] && a[i+3]!=a[i+2]) z=1;
else if(a[i+3]<=a[i+2]) z=1;
}
if(z==1) cout<<āNOT FAIRā<<endl;
else cout<<āFAIRā<<endl;
}
return 0;
}
Please format your code, or link to a solution - the forum software has mangled your code and it wonāt compile!
Consider the testcase:

#include<iostream>
using namespace std;
int main()
{
int T;
cin>>T;
while(T--)
{
int A[3],C[3];
for(int i=0;i<3;i++)
{
cin>>A[i];
}
for(int i=0;i<3;i++)
{
cin>>C[i];
}
for(int i = 1,j,key1,key2;i<3;i++)
{
j = i-1;
key1 = A[i];
key2 = C[i];
while(j >= 0 && key1 < A[j])
{
A[j+1]=A[j];
C[j+1] = C[j];
j--;
}
A[j+1] = key1;
C[j+1] = key2;
}
bool deal = true;
for(int i = 1;i<3;i++)
{
if(A[i]==A[i-1])
{
if(C[i]!=C[i-1])
{
deal = false;
break;
}
}
if(C[i-1] > C[i])
{
deal = false;
break;
}
}
if(deal)
{
cout<<"FAIR"<<endl;
}
else
{
cout<<"NOT FAIR"<<endl;
}
}
return 0;
}
I have sorted the age list/array and arranged the corresponding cost list/array, and then checked the fairness.
where Iām doing mistake that Iām resulting into a WA.
Thanks for formatting your code 
It fails on the following testcase:

I was doing such a silly mistakeā¦
thanks for the help buddy.

When you know what Integer.compare(int a, int b) doesā¦
static String isFair(int[] age, int[] amount) {
if((Integer.compare(age[0], age[1]) !=
Integer.compare(amount[0], amount[1]))
|| (Integer.compare(age[1], age[2])) !=
Integer.compare(amount[1], amount[2])
|| (Integer.compare(age[0], age[2])) !=
Integer.compare(amount[0], amount[2]))
return "NOT FAIR";
return "FAIR";

please help me, why it is giving me wrong answer. Atleast tell me, which test cases is not satisfy
- Your solution always prints an empty line before all the other outputs
