We have an array A of non-negative integers. For every (contiguous) subarray B = [A[i], A[i+1], ..., A[j]] (with i <= j), we take the bitwise OR of all the elements in B, obtaining a result A[i] | A[i+1] | ... | A[j]. Return the number of possible re…

附注: 1. Python中的按位运算符是把数字看作二进制来进行计算的.Python中的按位运算法则如下: 按位与 ( bitwise and of x and y ) & 举例: 5&3 = 1 解释: 101 11 相同位仅为个位1 ,故结果为 1 按位或 ( bitwise or of x and y ) | 举例: 5|3 = 7 解释: 101 11 出现1的位是 1 1 1,故结果为 111 按位异或 ( bitwise exclusive or of x…
