Hackerrank's Problem Solving solutions( Solve Me First, Simple Array Sum, Compare the Triplets ) :

Problem 1: Solve Me First

Solution: (in c++)

( please guys before moving to the solution try it yourself at least 3-4 times , if you really wanna become a good coder)

#include <bits/stdc++.h>

using namespace std;

int solveMeFirst(int a, int b)

{

return a+b;

}

int main()

{

int num1,num2;

cin>>num1>>num2;

int sum;

sum = solveMeFirst(num1,num2);

cout<<sum;

}

This code is simple. There's no need for any explanation.
 

 

 

 

Problem 2: Simple Array Sum

Solution: (in c++)

( please guys before moving to the solution try it yourself at least 3-4 times , if you really wanna become a good coder)

#include<bits/stdc++.h>

using namespace std;

int main()

{

int n,i,j,sum;

cin>>n;

int a[n];

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

cin>>a[i];

sum=0;

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

{

sum=sum+a[j];

}

cout<<sum;

}

This code is simple. There's no need for any explanation.
 

 

 

 

Problem 3: Compare the Triplets

Solution: (in c++)

( please guys before moving to the solution try it yourself at least 3-4 times , if you really wanna become a good coder)

#include<bits/stdc++.h>

using namespace std;

int main()

{

int c1=0,c2=0;

int a[3];

int b[3];

for(int i=0;i<3;i++)

{

cin>>a[i];

}

for(int k=0;k<3;k++)

{

cin>>b[k];

}

for(int j=0;j<3;j++)

{

if(a[j]>b[j])

{

c1++;

}

else if(a[j]==b[j])

{

c1=c1+0;

c2=c2+0;

}

else

{

c2++;

}

}

cout<<c1<<" "<<c2;

}

This code is simple. There's no need for any explanation.
