Min Max Sum Hackerrank

Posted on | Tuesday, 16 May 2023 | No Comments



 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.

Example

The minimum sum is  and the maximum sum is . 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  integers

Print

Print two space-separated integers on one line: the minimum sum and the maximum sum of  of  elements.

Input Format

A single line of five space-separated integers.

Constraints

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.)

Sample Input

1 2 3 4 5

Sample Output

10 14

Explanation

The numbers are , , , , and . Calculate the following sums using four of the five integers:

  1. Sum everything except , the sum is .
  2. Sum everything except , the sum is .
  3. Sum everything except , the sum is .
  4. Sum everything except , the sum is .
  5. Sum everything except , the sum is .

code:-
#!/bin/python3

import math
import os
import random
import re
import sys

#
# Complete the 'miniMaxSum' function below.
#
# The function accepts INTEGER_ARRAY arr as parameter.
#

def miniMaxSum(arr):
    # Write your code here
    c=sum(arr)-min(arr)
    d=(sum(arr)-max(arr))
    print(d,c)
if __name__ == '__main__':

    arr = list(map(int, input().rstrip().split()))

    miniMaxSum(arr)

Plus Minus Hackerrank

No Comments



Given an array of integers, calculate the ratios of its elements that are positive, negative, and zero. Print the decimal value of each fraction on a new line with  places after the decimal.

Note: This challenge introduces precision problems. The test cases are scaled to six decimal places, though answers with absolute error of up to  are acceptable.

Example

There are  elements, two positive, two negative and one zero. Their ratios are ,  and . Results are printed as:

0.400000
0.400000
0.200000

Function Description

Complete the plusMinus function in the editor below.

plusMinus has the following parameter(s):

  • int arr[n]: an array of integers

Print
Print the ratios of positive, negative and zero values in the array. Each value should be printed on a separate line with  digits after the decimal. The function should not return a value.

Input Format

The first line contains an integer, , the size of the array.
The second line contains  space-separated integers that describe .

Constraints


Output Format

Print the following  lines, each to  decimals:

  1. proportion of positive values
  2. proportion of negative values
  3. proportion of zeros

Sample Input

STDIN           Function
-----           --------
6               arr[] size n = 6
-4 3 -9 0 4 1   arr = [-4, 3, -9, 0, 4, 1]

Sample Output

0.500000
0.333333
0.166667

Explanation

There are  positive numbers,  negative numbers, and  zero in the array.

The proportions of occurrence are positive: , negative:  and zeros: .
