Alternatively, one could rewrite the previous code using the STLstd::mergealgorithm that could simplify the code for reading. Note that,std::mergefunction substitutes ourmergeimplementation, and vector merging can be accomplished with a single statement in themergeSortfunction body. When the final le...
I am trying to implement the Mergesort algorithm in C++. You can see my implementation below. When I run the algorithm I get the following error:libc++abi.dylib: terminating with uncaught exception of type std::out_of_range: vector Abort trap: 6 While this is my first time working in C...
(arrayOld, arrayNew, mid + 1, end); merge(arrayOld, arrayNew, start, mid, end); } } static void print(int arrayOld[], int n) { for (int i = 0; i < n; i++) { if (i == n - 1) { std::cout << arrayOld[i] << std::endl; } else { std::cout << arrayOld[i...
The first case that you check for in your 'merge step' of the merge sort -- if you have already merged all elements from the list second_half -- has the names of your two lists first_half and second_half switched around. Instead of this: if j >= len(first_half) and i < len(s...

Explore what is Merge Sort Algorithm in data structure. Read on to know how does it work, its implementation, advantages and disadvantages of Merge sort.
In Mergesort algorithm, we divide the input into three pieces of equal size( replace two pieces); solve the three subproblems on these pieces separately by recursion; and then combine the three results into an overall solution, spending only linear time for the initial division and final recombi...

algorithm 是C++标准程式库中的一个头文件,定义了C++ STL标准中的基础性的算法(均为函数模板)。在C++98中,共计有70个算法模板函数;在C++11中,增加了20个算法模板函数。其中有5个算法模板函数定义在头文件numeric中。 下文所称的“序列”(sequence),是指可以用迭代器顺序访问的容器。
