An array of data is stored in the general-purpose registers at addresses 0x20 to 0x4F of bank 0. Write an assembly program to search those registers to see if any of them contains the same data stored in M[0x50] of the same bank. The address of the first matching register is to be stored in M[0x51,0] while setting the most significant bit to 0. In case of no match, the most significant bit of M[0x51] is to be set to 1.
