Given two sorted integer arrays A and B, merge B into A as one sorted array. Note: You may assume that A has enough space (size that is greater or equal tom+n) to hold additional elements from B. The number of elements initialized in A and B aremandnrespectively. ...
The algorithms that we consider in this section are based on a simple operation known as merging : combining two ordered arrays to make one larger ordered array. This operation immediately leads to a simple recursive sort method known as mergesort : to sort an array, divide it into two halve...
