MergeSort uses divide & conquer strategy to sort the elements.
Here, you go on dividing till only one element is left.
Then this element will be merged with the next one and both will be put in correct order and since this is a recursive function, it will be repeated till you complete the merge and come out.
So, here is the sequence of calls:
a[] = {3, 5, 2, 6, 8}
low = 0; high = 4;
mergesort(a, 0, 4)
mid = 0 + 4 / 2 = 2
mergesort(a, 0, 2)
mergesort(a, 3, 4)
merge(a, 0, 4, 2)
Answer:
/* source of code from link above */
mergesort(int a[], int low, int high)
{
int mid;
if(low { mid=(low+high)/2; mergesort(a,low,mid); mergesort(a,mid+1,high); merge(a,low,high,mid); } return(0); } merge(int a[], int low, int high, int mid) { int i, j, k, c[50]; i=low; j=mid+1; k=low; while((i<=mid)&&(j<=high)) {
types of sorting in c language are: insertion sort selection sort bubble sort merge sort two way merge sort heap sort quick sort
There's only one type of sort in C++; std::sort. If you want other types you'll need to write your own.
The Express edition of C++ does not require a serial code. It is free.
The standard library sort algorithm automatically uses MSD radix to sort strings: std::vector<std::string> vs = {"a", "b", "c" "d", "ab"}; std::sort(vs.begin(), vs.end()); After sorting, the order will be: {"a", "ab", "b", "c", "d"}
No such code exists for MSEB Bill Generation in C++.
Top down merge sort is the easy way of merge sort in C language . It is used to derived o(n log n) algorithm . This is in par with the other methods.

Sometimes, it is. Some implementations compile C++ code into C code, and then compile the C code.

It is used to distinguish between the C or C++
All C++ source code is is a text file with the .cpp extension. So if you save your code as *****.cpp then it is automatically C++ source code.
