Trade unions or labour unions first appeared in Europe as a result of the industrial revolution. Workers
were at the mercy of the employer. They were underpaid, lacked any sort of training, and sometimes
mistreated. When trade unions emerged, they became powerful organisations. Workers got together
and organised themselves to make sure that employers do not exploit them anymore. Nowadays, the
main goal of trade unions is to negotiate labour contracts with employers. The leaders of trade unions
speak on behalf of workers and are predominantly worried about wages, working conditions and the
laws that govern the hiring, firing and promotion of workers. In some cases unions may call for strikes to
force employers to negotiate a deal or they may promote political legislation favourable to the interests
of their members or workers as a whole. To achieve this aim they may support and get closely linked to
particular political parties. Some people blame unions for creating tense atmosphere between
employers and employees. Others even accuse them of engendering relentless inflation. But the truth
is that the working conditions have changed tremendously since the industrial revolution. Unions have
contributed to considerably improve the standard of living. For instance, child labour is now prohibited
by law. What is more, unions have also been credited for introducing minimum wage limits and for
forbidding disreputable employers to exploit and mistreat their workers.

Programming
1.
Problem statement
Given an Integer N, write a program to reverse it.
Input Format
The first line contains an integer T, total number of testcases. Then follow T lines, each line contains an
integer N.
Constraints
1 ≤ T ≤ 1000
1 ≤ N ≤ 1000000
Output Format
For each test case, display the reverse of the given number N, in a new line.
Sample Input:
4
12345
31203
2123
2300
Sample Output:
54321
30213
3212
C CODE:
#include<stdio.h>
int main()
{ int t,i,d;
long a;
scanf("%d",&t);
while(t--)
{ long s=0;
scanf("%ld",&a);
while(a!=0){
d=a%10;
s=s*10+d;
a=a/10;
}
printf("%ld\n",s);
}
}
int main()
{ int t,i,d;
long a;
scanf("%d",&t);
while(t--)
{ long s=0;
scanf("%ld",&a);
while(a!=0){
d=a%10;
s=s*10+d;
a=a/10;
}
printf("%ld\n",s);
}
}

Problem statement
Creatnx now wants to decorate his house by flower pots. He plans to buy exactly N ones. He can only
buy them from Triracle's shop. There are only two kind of flower pots available in that shop. The shop is
very strange. If you buy X flower pots of kind 1 then you must pay A x X^2 and B x Y^2? if you buy Y
flower pots of kind 2. Please help Creatnx buys exactly N flower pots that minimizes money he pays.
Input Format
The first line contains a integer T denoting the number of test cases.
Each of test case is described in a single line containing three space-separated integers N, A, B.
Constraints
•1<T < 10^5
•1<N, A, B < 10^5
Output Format
For each test case, print a single line containing the answer.
Sample Input;
2
5 1 2
10 2 4
Sample Output:
17
134
c++ code:
#include <bits/stdc++.h>
#define ll long long int
using namespace std;
int main()
{
ll t; cin>>t; while(t--)
{
ll n,a,b;
cin>>n>>a>>b;
ll k=(b*n)/(a+b);
ll x=(a*k*k) + (b*(n-k)*(n-k));
k++;
ll y=(a*k*k) + (b*(n-k)*(n-k));
cout<<min(x,y)<<endl;
}
}
