In summary, Python provides a simple way to reverse a list by making use of the functionreversed(). You also can reverse a list manually by looping it in afororwhileloop. Python also has an easy method of reversing a list in a single line if you are comfortable using the slice operato...
We have to write a function that takes in an array and returns its reverse. Find its reverse using the for loop. Our sample array − const arr = [7, 2, 3, 4, 5, 7, 8, 12, -12, 43, 6]; So, let’s write the code for this function −...
