Ruby program to merge two integer arrays without using library function

Last Updated : December 15, 2025

Problem Solution

In this program, we will create two arrays of integers and then we will merge both arrays without using the library function.

Program/Source Code

The source code to merge two integer arrays without using the library function is given below. The given program is compiled and executed successfully.

# Ruby program to merge two integer arrays without 
# using library function

arr1 = [10,20,30,40,50];
arr2 = [60,70,80];
arr3 = Array.new(8);

count=0;
count1=0;

while(count<8)
    if(count<arr1.size)
        arr3[count]=arr1[count];
    else
        arr3[count]=arr2[count1];
        count1=count1 + 1;
    end
    count = count + 1;
end

print "Merged array: \n";
i=0;
while(i<8)
    print arr3[i]," ";
    i=i+1;
end

Output

Merged array: 
10 20 30 40 50 60 70 80 

Explanation

In the above program, we created two arrays of integer elements. Then we merged both arrays and assigned the result to the arr3 without using the library function. After that, we printed the merged array.
