Question

``Why is it that the JavaScript code is unable to find the maximum or minimum sum? Let's

function calculateMinMaxSums(arr) {
  // Custom code implementation
  let max = Math.max(...arr);
  let min = Math.min(...arr);
  let minsum = 0;
  let maxsum = 0;
  for (let x in arr) {
    if (arr[x] != max) {
      minsum += arr[x];
    };
    if (arr[x] != min) {
      maxsum += arr[x];
    }
  };
  console.log(minsum, maxsum);
}

This specific problem came up on hackerrank, and unfortunately it fails some of the test cases. However, I need to spend 5 "hackos" just to find out why.

Answer №1

Here is a simple code snippet

function findMinMax(arr) {
    var maxNumber = 0;
    var minNumber = 0;
    arr.sort();
    for(var i = 0;i<arr.length;i++){
        if(i>0 ){
            maxNumber = maxNumber + arr[i];
        }
        if(i<4){
            minNumber = minNumber + arr[i];
        }
    }
    console.log(minNumber + " " + maxNumber);
}

Give this code a shot!

 let userInput = prompt('Enter the desired number:');
let numArr = [];

for (i = 0; i < userInput; i++) {
    numArr.push(Number(prompt('Enter ' + i + 'th number:')));
}

let sum = 0;
const maximum = Math.max.apply(null, numArr);
const minimum = Math.min.apply(null, numArr);

for (i = 0; i < userInput; i++) {
    sum += numArr[i];
}

let avg = sum / userInput;

console.log(`The maximum value is ${maximum}`);
console.log(`The minimum value is ${minimum}`);
console.log(`The average value is ${avg}`);

Answer №3

Should each integer be distinct? If not, this method might fail with duplicate maximum and minimum numbers.

For instance [2,2,3,5,5]

After tackling this problem, I finally grasped its essence. Essentially, the task is to identify the four largest values in an array of integers, sum them up, and then find the sums of the four smallest values as well. (Check out the challenge on hackerrank: )

Below, you'll find the code with accompanying comments for clarity.

function miniMaxSum(arr) {
    // Create copies of the original array for max and min value calculations
    let arrMax = [...arr];
    let arrMin = [...arr];
    let maxSum = 0;
    let minSum = 0;

    // Find sums of the biggest and smallest 4 values
    for (let i = 0; i < 4; i++) {

        // Find index of element with the largest value
        let maxElementIndex = arrMax.findIndex(value => value === Math.max(...arrMax));
        // Add value to max sum
        maxSum += arrMax[maxElementIndex];
        // Remove value from array
        arrMax.splice(maxElementIndex,1);

        // Same process for finding the lowest value
        let minElementIndex = arrMin.findIndex(value => value === Math.min(...arrMin));
        minSum += arrMin[minElementIndex];
        arrMin.splice(minElementIndex,1);
    }
    console.log(`${minSum} ${maxSum}`);
}

These tips might be useful before posting a new question:

Include detailed information, such as explaining the problem more thoroughly before sharing your code.
Describe your understanding of the problem and what you're attempting to achieve, as it seems like a misunderstanding may have occurred.

If you encounter any difficulties, feel free to ask for clarification. Best of luck with your coding endeavors! :)
