Arrays, as foundational data structures in programming, exhibit two key characteristics: zero-based indexing and contiguous memory allocation. This guide explores essential algorithms for manipulating arrays, demonstrating efficient solutions to common problems.

Question: Array Search

Imagine an array nums of integers sorted in ascending order and a target integer. The task is to develop a function to search for target in nums. If target is found, return its index; otherwise, return -1.

Recursive algorithms are a fascinating aspect of computer science, often leading to elegant solutions to complex problems. To better understand their time complexity, let's delve into a simple example question.

Question: Calculating the nth Power of x

Solution 1: The Loop Method

A straightforward approach involves using a loop. Here's how it's implemented in Java:
