# Ruby program to sort an array in ascending order 
# using selection sort

arr = [12,39,49,87,68];

i=0;
j=0;
t=0;
min=0;

while(i<5)
    min=i;
    j=i + 1
    while(j<5)
        if(arr[j]<arr[min])
            min=j;
        end
        j=j + 1;
    end
    
    t=arr[i];
    arr[i]=arr[min];
    arr[min]=t;
    
    i=i + 1;
end

i=0;
print "Sorted Array in ascending order: \n";
while(i<5)
    print arr[i]," ";
    i=i+1;
end

Output:

Sorted Array in ascending order: 
12 39 49 68 87 

Explanation:

In the above program, we created an array of integer elements. Then we sorted the array elements in ascending order using the selection sort mechanism. After that, we printed the sorted array.
