WebJan 30, 2007 · select1st and select2nd are extensions provided by SGI. Their operator ()s take a std::pair as an argument, and return either the first member or the second member, respectively. They can be used (especially with the composition functors) to "strip" data from a sequence before performing the remainder of an algorithm. WebSimilarly we can generalise this for n. n& (-n) will contain only one set bit which is actually at the rightmost set bit position of n. Since there is only one set bit in n& (-n), it is a power of 2. So finally we can get the bit position by: log2 (n& (-n))+1. Share.
