WebDec 20, 2024 · In this post, we will discuss few such interesting bit manipulation hacks. Check if an integer is even or odd; Detect if two integers have opposite signs or not; Add 1 to an integer; WebNow it finally gets more interesting!!! Bit hacks #1 - #5 were kind of boring to be honest. This bit hack turns off the rightmost one-bit. For example, given an integer 001010 1 0 (the rightmost 1-bit in bold) it turns it into 00101000. Or given 00010000 it turns it into 0, as there is just a single 1-bit. population regulation definition

WebApr 9, 2016 · This method of finding modulus division by an integer that is one less than a power of 2 takes at most O (lg (N)) time, where N is the number of bits in the numerator (32 bits, for the code above). The number of operations is at most 12 + 9 * ceil (lg (N)).
