Learn how to reverse a string using recursion in Java with this step-by-step guide. Understand the recursive approach and see practical examples.
Following are the steps to reverse a string using stacks in the Main method ? First, import all the classes from the java.util package. We will define the input string. Convert the string into a character array. Push each character into the stack. Pop characters from the stack to reverse...
The depth of the recursion is equal to the length of the String. This solution is not the best one and will be really slow if the String is very long and the stack size is of major concern. Approach 6 – Using two pointers function revStr(str) { let arr = new Array(str.length) ...
ReverseArrayList.reverseWithRecursion(aList); assertThat(aList).isEqualTo(EXPECTED); If we run the test, it passes. So, our recursion implementation solves the problem. 5. Reversing aListUsing Iteration We’ve just reversed the list using recursion. Alternatively, we can solve the problem using...
