Day 3: Arrays

 Day 3: Arrays || Hackerrank Soluiton

Objective

In this challenge, we learn about Arrays. Check out the attached tutorial for more details.

Task

Complete the getSecondLargest function in the editor below. It has one parameter: an array, , of  numbers. The function must find and return the second largest number in .

Input Format

Locked stub code in the editor reads the following input from stdin and passes it to the function:
The first line contains an integer, , denoting the size of the  array.
The second line contains  space-separated numbers describing the elements in .

Constraints

• , where  is the number at index .
• The numbers in  are not distinct.

Output Format

Return the value of the second largest number in the  array.

Sample Input 0

5
2 3 6 6 5

Sample Output 0

5

Explanation 0

Given the array , we see that the largest value in the array is  and the second largest value is . Thus, we return  as our answer.

Soluiton

function getSecondLargest(nums) {
    const n=parseInt(readLine());
   var flargest =nums[0];
   var slargest;
   nums.forEach(function(e,i){
       if(nums[i]>flargest){
           slargest=flargest;
           flargest=nums[i];
         }
         else if (nums[i] > slargest && nums[i] != flargest) 
            slargest = nums[i]; 
   });
return slargest;
}
