My implementation is slow and therefore needs some modifications. Problem is to merge them into a new final stack, such that the elements. Array supports random access, which means elements can be accessed directly using their index, like arr0 for 1st element, arr6 for 7th element etc. The first while loop repeats so long as each input stack has at least one element.
If, however, the arrays contain numeric keys, the later value will not. If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. Arrays are index based data structure where each element associated with an index. Algorithms for beginners bubble sort, insertion sort. Merge sort algorithm is a generalpurpose comparisonbased sorting algorithm. On the other hand, linked list relies on references where each node consists of the data and the references to the previous and next element.

Using peek to look at the top entries of the stack, the smaller of the two stack tops is popped and pushed onto the output. The major difference between linear search and binary search is that binary search takes less time to search an element from the sorted list of elements.
