WebTo toggle a bit, you use the XOR operator. Like with the other methods, create the position bitmask, but this time, ^= (XOR equal) the value. 06:56 Remember that if both bits are … WebWe can convert 10 to 7 in 3 steps: - Flip the first bit from the right: 101 0 -> 101 1 . - Flip the third bit from the right: 1 0 11 -> 1 1 11. - Flip the fourth bit from the right: 1 111 -> 0 111. It can be shown we cannot convert 10 to 7 in less than 3 steps. Hence, we return 3. Input: start = 3, goal = 4 Output: 3 Explanation: The binary ...
