一句话 / Summary: Q1的MIPS版本
You have been given 22t2final_q2.s , a MIPS assembler program that reads an integer and then prints 42.
Add code to 22t2final_q2.s so that it prints the amount of zero bits in the integer that was read in.
In other words, it should behave the same as final_q1 .
For example:
1521 mipsy 22t2final_q2.s 0 32 1521 mipsy 22t2final_q2.s 1 31 1521 mipsy 22t2final_q2.s 100000 26 1521 mipsy 22t2final_q2.s -1 0
Your program can assume its input only contains only 1 integer.
Your program can assume that the integer will fit in a MIPS register .
Your solution must be in MIPS only.
Your solution must not be in C , C++ , Python , or any other language.
No error checking is necessary or required.
🤖 Write MIPS (mipsy). Read one integer, print the number of 0 bits in its 32-bit representation.
Verified on the sandbox AND cross-checked against an independent oracle (official examples included).
