Recursion with bitwise operators
I have the following method in java that simplify Nor expressions using recursion: Now, when I want to simplify the expression (T ↓ y) ↓ y , it ouputs F ↓ y instead of ~(y). How I need to change the recursion to output the right simplified expression? Answer Your case isn’t covered, so you get the default, all the
Bitwise packing/unpacking – generalized solution for arbitrary values
I’m trying to adapt this answer to arbitrary numeric values. Let’s say we have 3 (unsigned) numbers: v1, v2, v3 and we know the respective max values they may have: max1, max2, max3. max1 * max2 * max3 < 2^32, so the result (packed value) is to be within 32 bits. How to pack/unpack them without “magic” hardcoding? Answer Here
Bitwise operator for simply flipping all bits in an integer?
I have to flip all bits in a binary representation of an integer. Given: The output should be What is the bitwise operator to accomplish this when used with an integer? For example, if I were writing a method like int flipBits(int n);, what would go in the body? I need to flip only what’s already present in the number,
