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

Last Updated : December 15, 2025

Problem Solution

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

Program/Source Code

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

# 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.
