既然时二进制的表示,那么我们就把这个当作二进制来求所以这个时候枚举就是从0到1,然后我们需要一个数来表示这个二进制中1的个数,还需要一个数来表示这个数的大小 这样子dp就应该比较好定义了,dp[i][j][k] 第i位,这个数的大小,其中二进制含有1 的个数。 但是这个数字可以非常大,难道我们就定义一个超级大...

I've got a solution that counts the bits in O(Number of 1's) time: bitcount(n): count = 0 while n > 0: count = count + 1 n = n & (n-1) return count In worst case (when the number is 2^n - 1, all 1's in binary) it will check every bit. Edit: Just found a ...

How it works: essentially all we are doing here is vectorizing the original loop so that we process 4 bits per loop iteration instead of 1. So we now have 16 loop iterations instead of 64. For each iteration we load 4 bits from bits, then use them as an index into...
