How to improve computation time using STL a container Vector??

Question

Accepted Answer

Using STL container Vector can improve computation time by providing efficient dynamic memory allocation and access.

Use reserve() function to preallocate memory for the vector to avoid frequent reallocation.
Avoid inserting or erasing elements in the middle of the vector as it requires shifting elements.
Use emplace_back() instead of push_back() for better performance when constructing objects.
Consider using vector instead of vector for memory optimization.
Use iterators instead of indexing for accessing elements to avoid bounds checking.
Sort the vector using sort() function for faster searching or binary search.
Use parallel algorithms like parallel_sort() for large vectors to utilize multiple cores.
Avoid unnecessary copying of vectors by passing them by reference or using move semantics.
