WebApr 27, 2024 · A mask determines which bits to take and which bits to clear off a binary number. Bitmasking can be used to mask a value to represent the subsets of a set using various bitwise operations. The concept of bitmasking is used along with dynamic programming to solve a wide range of problems. 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.
