When converting a traditional sequential program to make it run as a parallelizable program, you need to consider four things as Partitioning, Communication, Synchronization, and Load balancing. Convert the following for-loop to make it run in two threads in consideration of partitioning. Assume that data is located in the array A[]. You must use std::thread(). A summation function needs to be defined as a lambda expression. double sum = 0; for (int i = 0; i < 100000; i++) sum += A[i];
