Problem Solution:

In this program, we will create an array of integers and then we will read an item from the user and insert the input item into the array.

Program/Source Code:

The source code to insert an item into the array without using the library function is given below. The given program is compiled and executed successfully.

# Ruby program to insert an item into array without 
# using library function

arr = [10,20,30,40,50];

print "Enter item: ";
item = gets.chomp.to_i;  

i = 0;
while (i < 6) 
    if (arr[i] >= item) 
      j = 4;
      while (j >= i) 
        arr[j + 1] = arr[j];
        j = j - 1;
      end
      arr[i] = item;
      break;
    end
    i = i + 1;
end
      
print "Array elements after insertion: \n";
i=0;
while(i<6)
    print arr[i]," ";
    i=i+1;
end

Output:

Enter item: 35

Array elements after deletion: 
10 20 30 35 40 50

Explanation:

In the above program, we created an array of integer elements. Then we read an item from the user. After that, we inserted the input item into the array without using the library function. After that, we printed the updated array.
