Submitted by Nidhi, on January 21, 2022

Problem Solution:

In this program, we will create an array of integers and then we will sort the created array in descending order using bubble sort.

Program/Source Code:

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

# Ruby program to sort an array in descending 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 in descending order: \n";
i=0;
while(i<5)
    print arr[i]," ";
    i=i+1;
end

Output:

Sorted Array in descending order: 
87 69 68 49 12  

Explanation:

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