+/**
+ * @file
+ * @brief Implementation of the Unbounded 0/1 Knapsack Problem
+ * 
+ * @details 
+ * The Unbounded 0/1 Knapsack problem allows taking unlimited quantities of each item. 
+ * The goal is to maximize the total value without exceeding the given knapsack capacity. 
+ * Unlike the 0/1 knapsack, where each item can be taken only once, in this variation, 
+ * any item can be picked any number of times as long as the total weight stays within 
+ * the knapsack's capacity.
+ * 
+ * Given a set of N items, each with a weight and a value, represented by the arrays 
+ * `wt` and `val` respectively, and a knapsack with a weight limit W, the task is to 
+ * fill the knapsack to maximize the total value.
+ *
+ * @note weight and value of items is greater than zero 
+ *
+ * ### Algorithm
+ * The approach uses dynamic programming to build a solution iteratively. 
+ * A 2D array is used for memoization to store intermediate results, allowing 
+ * the function to avoid redundant calculations.
+ * 
+ * @author [Sanskruti Yeole](https://github.com/yeolesanskruti)

+ * @brief Adds two binary numbers and outputs resulting string

+ * @details The algorithm for adding two binary strings works by processing them

+ * longer string's length to ensure both strings are fully traversed. For each
+ * pair of corresponding bits and any carry from the previous addition, it
+ * calculates the sum. If the sum exceeds 1, a carry is generated for the next
+ * bit. The results for each bit are collected in a result string, which is
+ * reversed at the end to present the final binary sum correctly. Additionally,
+ * the function validates the input to ensure that only valid binary strings
+ * (containing only '0' and '1') are processed. If invalid input is detected,
+ * it returns an empty string.
