WebOct 19, 2024 · Bit Operations We can use & operator to check if a number is even or odd. If x & 1 = 0 then x is even and if x & 1 = 1 then x is odd. We can also say that, x is divisible by 2 k exactly when x & (2 k – 1) = 0. x<>k corresponds to dividing x by 2 k rounded down to an integer.

"WebOct 31, 2024 · A big advantage of bit manipulation is that it is trivial to iterate over all the subsets of an N-element set: every N-bit value represents some subset. Even better, if A is a subset of B then the number representing A is less than that representing B, which is convenient for some dynamic programming solutions. " - Bit field manipulation
