Ruby program to sort an array in ascending order using bubble sort

Program/Source Code:

The source code to sort an array in ascending order using bubble sort is given below. The given program is compiled and executed successfully.

# Ruby program to sort an array in ascending order 
# using bubble Sort

arr = [12,69,49,87,68];

i=0;

while (i < 5)
  j = 4;
  while (j > i) 
    if (arr[j] < arr[j - 1]) 
      t = arr[j];
      arr[j] = arr[j - 1];
      arr[j - 1] = t;
    end
    j = j - 1
  end
  i = i + 1
end

print "Sorted Array: \n";
i=0;

while(i<5)
    print arr[i]," ";
    i=i+1;
end

Output:

Sorted Array: 
12 49 68 69 87 

Explanation:

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