WebMay 27, 2024 · Given a non-negative number n and two values l and r. The problem is to set the bits in the range l to r in the binary representation of n, i.e, to unset bits from the rightmost lth bit to the rightmost r-th bit. Constraint: 1 <= l <= r <= number of bits in the binary representation of n. Examples : Web6 Answers. Sorted by: 10. Assuming value is 0 or 1: REG = (REG & ~ (1 << pin)) (value << pin); I use REG instead of register because as @KerrekSB pointed out in OP comments, register is a C keyword. The idea here is we compute a value of REG with the specified bit cleared and then depending on value we set the bit.
