Explanation
Step 1: 1’s Complement nikaalein
1’s complement nikaalne ke liye saare 1 ko 0 aur 0 ko 1 mein badal dete hain (Inversion).
Step 2: LSB (Least Significant Bit) mein 1 add karein
2’s complement ka formula hota hai:
Ab hum calculation karte hain:
\begin{array}{r@{\quad}l}</p> <p data-path-to-node="10">& 0100100 \quad \text{(1's complement)} \</p> <ul data-path-to-node="11"> <li> <p data-path-to-node="11,0,0">& 0000001 \quad \text{(Add 1)} \</p> <p data-path-to-node="11,0,0">\hline</p> <p data-path-to-node="11,0,0">& 0100101 \</p> <p data-path-to-node="11,0,0">\hline</p> <p data-path-to-node="11,0,0">\end{array}
Final Answer
The 2’s complement of 1011011 is 0100101.
