Find the Minimum and Maximum Sum

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.

Sample Input

1 2 3 4 5

Sample Output

10 14

1. Find the Minimum and Maximum Element in array
2. When you calculate the minSum and maxSum – discard the maxElement and minElement
3. Trick is you may miss logic if the array contains 5 elements and all are of same value. In such case the maximum and minimum value elements are same
4. For finding minimum number, start by assigning maximum number to minNum

 public static void miniMaxSum(List<Integer> arr) {
        long minNum = 0;
        long maxNum = 0;

        long minSum = 0;
        long maxSum = 0;


        //To find maximum Number
        for(int num=0;num<arr.size();num++){
            if(maxNum<=arr.get(num)){
                maxNum = arr.get(num);
            }
        }

        //To find minimum Number
        minNum = maxNum;

        for(int num=0;num<arr.size();num++){
            if(arr.get(num)<=minNum){
                minNum = arr.get(num);
            }
        }

        for(int num=0;num<arr.size();num++){
            //If the array elements are of same value
            if(num!=0 && arr.get(num) == arr.get(num-1)){
                minSum +=arr.get(num);
                maxSum +=arr.get(num);
            }


            if(arr.get(num) != maxNum)
              minSum +=arr.get(num);

            if(arr.get(num) != minNum)
              maxSum +=arr.get(num);
        }

        System.out.println(minSum);
        System.out.println(maxSum);
    }

Get Count of biggest Element in array – Total Tallest Candles to be blown

Input Format
Array of Integers

Constraints

   

Output Format
Count of Biggest Element in array

Sample Input

3 2 1 3 5 6 5 4 5

Sample Output

1

1. In the above example 6 is the biggest element and it occurs only once
2. Find the biggest element in array
3. Find the count of the biggest element

public static int birthdayCakeCandles(List<Integer> candles) {
        // Write your code here
        long tallestCandle = 0;
        int tallestCandleCnt = 0;

        for(int num=0;num<candles.size();num++){
            if(tallestCandle<=candles.get(num)){
                tallestCandle = candles.get(num);
            }
        }

        for(int num=0;num<candles.size();num++){
            if(candles.get(num) == tallestCandle)
                tallestCandleCnt +=1;
        }

        return tallestCandleCnt;
    }
