Write an ARM assembly program that copies the 64-bit integers in array sourceArr

Question

Write an ARM assembly program that copies the 64-bit integers in array sourceArray into a destination array beginning at location 0x40000000 removing duplicate array entries in the process.  Hint: read a number from sourceArray and write it to the next available location in the destination array if it is new.  If the number is already in the destination array, ignore it.  Both arrays are of type DCQ. The DCQ directive allocates one or more eight-byte blocks of memory, aligned on four-byte boundaries, and defines the initial runtime contents of the memory. Copy and paste sourceArray into your program.
