WebIntroduction. Let's learn bitwise operations that are useful in Competitive Programming. Prerequisite is knowing the binary system. For example, the following must be clear for you already. 13 = 1 ⋅ 8 + 1 ⋅ 4 + 0 ⋅ 2 + 1 ⋅ 1 = 1101 ( 2) = 00001101 ( 2) Keep in mind that we can pad a number with leading zeros to get the length equal to ... WebJan 24, 2024 · Bits that are shifted off the end of the binary number are lost forever. The bitwise right shift (>>) operator shifts bits to the right. 1100 >> 1 is 0110. 1100 >> 2 is 0011. 1100 >> 3 is 0001. Note that in the third case we shifted a …
