Can anyone provide the new link to the ICO whatsapp group?? The link given in this site as well as at Codechef has expired.

C++ STL (MAP ) SOLUTION:-

#include<bits/stdc++.h>

using namespace std;

typedef long long int lli;

int main() {

lli N,M,K;

cin>>N>>M>>K;

std::map<lli, lli>ALL;

for(int i=0;i<(N+M+K);i++){

lli o;

cin>>o;

ALL[o]++;

#include<bits/stdc++.h>

using namespace std;

int main()

{

long n,i,crane_pos=0,crane_occ=0;

long long h;

int move;

cin>>n>>h;

vector<long long> inp(n);

for(i=0;i<n;i++)

{

scanf("%d",&inp[i]);
