Using "#define" in pair<>!!

main.cpp
main.cpp 
TO quickly type we can use #define in pair like this: 
 
#define pii pair<int,int> 
#define ppi pair<pii,int> 
#define ppp pair<pii,pii> 
#define ss second 
#define ff first 
 
CODE: 
 
#include <bits/stdc++.h>
using namespace std;
#define ll long long
#define pii pair<int,int> 
#define ppi pair<pii,int> 
#define ppp pair<pii,pii> 
#define ss second 
#define ff first 
 
int main() 
{ 
    pii p1; 
    ppi p2; 
    cin>>p1.ff>>p1.ss; 
    p2=ppi(p1,p1.ss*p1.ff); 
    cout<<"Entry: "<<p2.ff.ff<<" , "<<p2.ff.ss<<endl; 
    cout<<"Product: "<<p2.ss<<endl;    return 0; 
}

SPOJ-INVERSE-SORT

Problem Algorithm: We have to generate  10!  combination of " abcdefghij  " by reversing and put appropriate distance from " abcdefghij  " So we need  key(string)->value  data structure. First thing comes to our mind is map<string,int> But it uses O(logN) time to insert a value as everything is ordered here So we use unordered_map ( Normally o(1) highest o(n) barely )  After that we take 2 string input and then find the relative string S from s1->s2 and another AC!! CODE Time needed 40-45sec .
