In order to make the array reversible, you have to make it mutable using the var keyword. Step 1 ? Create a mutable input array to iterate Step 2 ? Call the reverse() function to reverse the array elements Step 3 ? Perform an action on each element of an array inside the for-loop ...
print("Reversed array is:", rev_arr) Output: 1 2 3 4 Original array is: [10, 20, 30, 40, 50, 60] Reversed array is: [60, 50, 40, 30, 20, 10] Using array modile Now, we will see different ways to reverse an array using array module in Python. Using a reverse() method...

We created an object Sample, and we defined main() function. The main() function is the entry point for the program.In the main() function, we created two integer arrays IntArray, RevArray. The IntArray contains 5 integer elements. Then we copied the elements of IntArray into RevArray ...
In the first line the array is defined. Then with the size variable, we will store the length of the array. After that, we traverse the loop in reverse order, which is starting with "size-1" index, which is 4 in our case and we are iterating till the 0th index. Inside the loop...
