Mini-Max Sum
Problem Statement :
Given five positive integers, find the minimum and maximum values that can be calculated by summing exactly four of the five integers. Then print the respective minimum and maximum values as a single line of two space-separated long integers.
arr = [1,3,5,7,9]
Example
The minimum sum is 1 + 3 + 5 + 7 = 16 and the maximum sum is 3 + 5 + 7 + 9 = 24.
the function prints 16 24 .
Function Description
Complete the miniMaxSum function in the editor below.
miniMaxSum has the following parameter(s):
arr: an array of 5 integers
Print Print two space-separated integers on one line: the minimum sum and the maximum sum of 4 of 5 elements.
Input Format
A single line of five space-separated integers.
Constraints
1 <= arr[i] <=10^9
Output Format
Print two space-separated long integers denoting the respective minimum and maximum values that can be calculated by summing exactly four of the five integers. (The output can be greater than a 32 bit integer.)
Solution :
Solution in C :
In C :
void miniMaxSum(int arr_count, int* arr) {
int min = arr[0] , max;
int j;
for(int i=0; i < arr_count-1;i++)
{
for(int j=0; j< arr_count-i-1; j++)
{
if(arr[j] > arr[j+1])
{
min = arr[j];
arr[j] = arr[j+1];
arr[j+1] = min;
}
}
}
long int minimal_sum = 0, max_sum = 0;
for(int i = 0; i< arr_count-1;i++ )
{
minimal_sum += arr[i];
}
for(int j = 1; j< arr_count;j++ )
{
max_sum += arr[j];
}
printf("%ld %ld",minimal_sum,max_sum);
}
In Python3 :
a = input().strip().split(' ')
for i in range(0, len(a)):
a[i] = int(a[i])
s = sum(a)
print(str(s - max(a)) + " " + str(s - min(a)))
In C ++ :
#include <bits/stdc++.h>
typedef long long LL;
using namespace std;
int main(){
LL s[5];
LL d = 0;
for(int i = 0; i < 5; i++){
cin >> s[i];
d += s[i];
}
sort(s,s+5);
cout << d-s[4] << " " << d-s[0] << endl;
