WebBy default the 'left shift' operation in Python ( << ) acts as an arithmetic shift and appends a 0 bit to the end of the bits representing the int. For example: 100 << 1 returns 200. In the binary representation we can see that 100 = 0b1100100 (7 bits) and 100 << 1 = 0b11001000 (8 bits) WebNov 25, 2013 · Add a comment. 2. First find the length of the binary number by log2 (n) logarithm in base 2 of n. n = 6 l = int (log (n, 2)) + 1. As your number is 6 which is 110 in binary find the MSB 100 (4 in decimal). mask = 2** (l-1) #msb will always be 2^ (length-1) Now simply use XOR operator to remove the MSB. res = n^mask.
