//bubble sort

#include<iostream>
using namespace std;
int main()
{
    int n, i, arr[50], j, temp;
    cout<<"Enter the Size (max. 50): ";
    cin>>n;
    cout<<"Enter "<<n<<" Numbers: ";
    for(i=0; i<n; i++)
        cin>>arr[i];
    cout<<"\nSorting the Array using Bubble Sort Technique..\n";
    for(i=0; i<(n-1); i++)
    {
        for(j=0; j<(n-i-1); j++)
        {
            if(arr[j]>arr[j+1])
            {
                temp = arr[j];
                arr[j] = arr[j+1];
                arr[j+1] = temp;
            }
        }
    }
    cout<<"\nArray Sorted Successfully!\n";
    cout<<"\nThe New Array is: \n";
    for(i=0; i<n; i++)
        cout<<arr[i]<<" ";
    cout<<endl;
    return 0;
}

//Selection sort

#include<iostream>
 
using namespace std;
 
int main()
{
    int i,j,n,loc,temp,min,a[30];
    cout<<"Enter the number of elements:";
    cin>>n;
    cout<<"\nEnter the elements\n";
 
    for(i=0;i<n;i++)
    {
        cin>>a[i];
    }
 
    for(i=0;i<n-1;i++)
    {
        min=a[i];
        loc=i;
        for(j=i+1;j<n;j++)
        {
            if(min>a[j])
            {
                min=a[j];
                loc=j;
            }
        }
 
        temp=a[i];
        a[i]=a[loc];
        a[loc]=temp;
    }
 
    cout<<"\nSorted list is as follows\n";
    for(i=0;i<n;i++)
    {
        cout<<a[i]<<" ";
    }
 
    return 0;
