Bitwise or of subarrays
WebFor each array element ending at jth index compute suffixes of all bitwise or values ending at jth index. For example take array = [3,1,4,2,6] If we take j = 5 (1 based indexing) arr[5]=6 compute all bitwise or [7,7,6,6,6] So in the range (1,2) make range update with value 7. In the range (3,5) make range update with value 6. WebValue of a subarray is defined as BITWISE OR of all elements in it. Return the sum of Value of all subarrays of A % 10^9 + 7. Input Format. The first argument given is the integer array A. Output Format. Return the sum of Value of all subarrays of A % 10^9 + 7. Constraints.
