QUESTION

You have been given an array A of size N you need to sort this array non-decreasing order using bubble sort. However, you do not need to print the sorted array . You just need to print the number of swaps required to sort this array using bubble sort\n\nInput Format\n\nThe first line consists of a single integer N\nN denoting size of the array. The next line contains N space separated integers denoting the elements of the array.\n\nOutput Format Print the required answer in a single line\n\nConstraints \n1<=N<=100\n1<=a[i]<=100.

ANSWER

#include <iostream>
using namespace std;
int main()
{int n,arr[100],count=0;
 cin>>n;
 for(int i=0;i<n;i++)
   cin>>arr[i];
 for(int i=0;i<n-1;i++)
 {for(int j=0;j<n-i-1;j++)
  {if(arr[j]>arr[j+1])
   {int temp=arr[j];
    arr[j]=arr[j+1];
    arr[j+1]=temp;
    count++;
   }
  }
 }
cout<<count;
 
 

	return 0;
}
