Swift Program to Reverse a String Using Stacks - A stack is a data structure which works on LIFO(last in first out) principle. It is used to store and manage data where the recently added item is the first one to be removed from the stack. Stack support
import java.util.Stack; public class Reverse_a_stack_using_recursion { /* Input stack: 3 2 1 Output stack: 1 2 3 */ public static void main(String[] args) { Stack<Integer> s = new Stack<Integer>(); s.push(1); s.push(2); s.push(3); insertAtBottom(s, 4); System.out.pri...
Using the Java regex API, you find the numbers, their start position and the end positions which you can use to build the required string. Demo: import java.util.regex.Matcher; import java.util.regex.Pattern; public class Main { public static void main(String[] args) { // Tests String...
Believe it or not, after profiling my current code, the repetitive operation of numpy array reversion ate a giant chunk of the running time. What I have right now is the common view-based method: reversed_arr = arr[::-1] Is there any other way to do it more efficiently, or is it...

In Python, we also have another number data type called octal and hexadecimal numbers. To represent the octal number which has base 8 in Python, add a preceding 0 (zero) so that the Python interpreter can recognize that we want the value to be in base 8 and not in base 10. Example:...
