    • Method Detail

      • getNumBitsPerValue

        public static int getNumBitsPerValue​(int maxValue)
        Returns the number of bits required to encode the value.

        NOTE: Use at least one bit even there is only one possible value

        Examples: (maximum value (binary format) -> number of bits)

        • 0(0) -> 1
        • 1(1) -> 1
        • 2(10) -> 2
        • 9(1001) -> 4
        • 113(1110001) -> 7
        Parameters:
        maxValue - Maximum possible value
        Returns:
        Number of bits required to encode the value
