Divide and conquer algorithms decompose complex problems into smaller sub-parts, where a defined solution is applied recursively to each sub-part.
WebApr 6, 2024 · Conclusion: In summary, a custom assignment operator in C++ can be useful in cases where the default operator is insufficient or when resource management, memory allocation, or inheritance requires special attention. It can help avoid issues such as memory leaks, shallow copies, or undesired behaviour due to differences in object states.

WebFind middle = (left + right)/2. Call mergeSort (arr, left, middle) to recursively sort the first half of the array. Similarly, call mergeSort (arr, middle+1, right) to recursively sort the other half of the array. Finally call merge (arr, left, middle, right) to merge the obtained sorted arrays. Now, the given array is sorted.
