WebAdd up the two lengths, then use a syscall 9 to allocate heap memory for your c array. Then, for copying, I'd suggest writing a function that takes two arrays, an index and copies an element from the first to the second at that index. Then write some code to iterate through each source array, calling the copy function on every iteration.
