Question

The user will input an unsorted integer array and the method should find the third largest integer in the array. input: 3 ,6, 9, 8, 0

Jignesh Kumar · Answer

Please check below one, int largestNumberAtPosion = 3; int[] intArray = { 3, 6, 9, 8, 0 }; var sortedArray = intArray.OrderByDescending(x => x); var topNumber = sortedArray.Skip(largestNumberAtPosion - 1).Take(1).FirstOrDefault();

Amit Mohanty · Answer

Try this int[] array = { 3, 6, 9, 8, 0 }; Array.Sort(array); int elementCount = 0; int? thirdLargestNumber = null; foreach (var element in array) { var temp = array.Skip(elementCount).ToArray(); if (temp.Length == 3) { thirdLargestNumber = temp[0]; break; } elementCount++; } Console.WriteLine($"Third largest number = {thirdLargestNumber}");

Pls follow the steps 1.get it as list 2. Sort it as descending using lambda 3. Then apply Skip(2).Take(1) => It will skip 0,1 index and take 2 index value. 4. Another option after skip apply firstordefaultvaule. Both yield the same result

public class ThirdLargestInArrayExample{ public static int getThirdLargest(int[] a, int total){ int temp; for (int i = 0; i a[j]) { temp = a[i]; a[i] = a[j]; a[j] = temp; } } } return a[total-3]; } public static void main(String args[]){ int c[]={3,6,9,8,0}; int a[]={1,2,5,6,3,2}; int b[]={44,66,99,77,33,22,55}; System.out.println("Third Largest: "+getThirdLargest(c,5)); System.out.println("Third Largest: "+getThirdLargest(a,6)); System.out.println("Third Largest: "+getThirdLargest(b,7)); }} Output : Third Largest:6 Third Largest:3 Third Largest:66

Try this public class Program { public static void Main() { int[] unsortedArray = new int[5] {3 ,6, 9, 8, 0}; Console.WriteLine("Input UnSorted Array: "); Console.WriteLine("------------------------------------------------ "); for( int i = 0; i
