"WebConditional Assignments vs. Bitwise Operations. One of the most frequently-used techniques in branchless programming is replacing conditional assignments with bitwise operations. Bitwise operations directly manipulate the bits that represent the data in a computer’s memory, making them very efficient and suitable for performance-critical code. " - Bitwise operation mask

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 ... WebMay 27, 2024 · 1) Clear all bits from LSB to ith bit mask = ~ ( (1 << i+1 ) - 1); x &= mask; Logic: To clear all bits from LSB to i-th bit, we have to AND x with mask having LSB to i-th bit 0. To obtain such mask, first left shift 1 i times. Now if we minus 1 from that, all the bits from 0 to i-1 become 1 and remaining bits become 0.
