WebJun 15, 2024 · Python Count set bits in a range. Given a non-negative number n and two values l and r. The problem is to count the number of set bits in the range l to r in the binary representation of n, i.e, to count set bits from the rightmost lth bit to the rightmost rth bit. Constraint: 1 <= l <= r <= number of bits in the binary representation of n. Web49. You just need: def set_bit (v, index, x): """Set the index:th bit of v to 1 if x is truthy, else to 0, and return the new value.""" mask = 1 << index # Compute mask, an integer with just bit 'index' set. v &= ~mask # Clear the bit indicated by the mask (if x is False) if x: v = mask # If x was True, set the bit indicated by the mask ...
