HackerRank Solution For Mini-Max Sum in C++

Problem:- Hacker Rank Solution Program In C++ For " Mini-Max Sum " or Hacker Rank Solution Program In C++ For Mini-Max Sum or Mini-Max Sum solution hacker rank or Hacker rank solution for c++ domain or Hacker rank solution for Mini-Max Sum subdomain or Mini-Max Sum solution in c++ of hacker rank.

Logic:- This min-max sum problem is very popular and important in hacker rank. In min-max sum problem, we have 5 number as input and we have to find the sum of 4 elements in this way that 4 number out of 5 number sum should be maximum and same for a minimum sum of an array. I am going to tell to problem statement step by step with full explanation trust me this is the simplest problem. First, take an input of any number by user after that add all number and sort the array and after sorting an array remove first index element and last index element from an array if you get than ok if not see the below full explanation of the problem min-max sum 

Explanation:- The First step is to take an input from user and after that take another variable add the all 5 number of an array and store the sum of 5 variable in sum name variable for better understanding let's take an example suppose array 5 elements are 2, 5, 1, 4, 3.

for(i=0; i<5; i++)
        //cout<<sum<<" ";

Total sum of 5 elements is = 15

So the sum of the 5 variables in an array is 15, Now next step to sort the array, for sorting I am using sort function of a vector by default it sorts an array ascending order for our array element become after sorting.

Sort function of a vector 

sort(array.begin(), array.end());

After sorting element of an array

1, 2, 3, 4, 5 

Note:- You can use here Bubble Sort, Selection Sort, Insertion Sort and many others

Now we know that small element and big element in the array so just minus the small and big element of an array in this way we can get a Min-Max Sum of an array.

Max sum = sum - array[array first index element]

Min-Sum = sum - array[array last index element]

Max sum = 15 - 1 = 14

Min-Sum = 15 - 5 = 10

So hence we get our answer according to problem statements in hacker rank.

Tip:- Before copy the program I recommended please read this full article, this will help you to build your own logic. Solve the problem by using above any sorting like- Bubble Sort, Selection Sort, Insertion Sort.


#include <bits/stdc++.h>
using namespace std;

int main() 
int val,i;
long long int sum=0;

vector<int> array;

for(i=0; i<5; i++)
        //cout<<sum<<" ";

        sort(array.begin(), array.end());   
/*for(i=0; i<5; i++)
        cout<<sum-array[4]<<" "<<sum-array[0];  
        return 0;
