text: Sum of Bitwise AND of each array element with the elements of another array | Function to compute the AND sum for each element of an array ; Declaring an array of size 32 for storing the count of each bit ; Traverse the array arr2 [ ] and store the count of a bit in frequency array ; Current bit position ; While num is greater than 0 ; Checks if ith bit is set or not ; Increment the count of bit by one ; Increment the bit position by one ; Right shift the num by one ; Traverse in the arr2 [ ] ; Store the ith bit value ; Total required sum ; Traverse in the range [ 0 , 31 ] ; Checks if current bit is set ; Increment the bitwise sum by frequency [ bit_position ] * value_at_that_bit ; ; Right shift num by one ; Left shift vale_at_that_bit by one ; Print the sum obtained for ith number in arr1 [ ] ; Given arr1 [ ] ; Given arr2 [ ] ; Size of arr1 [ ] ; Size of arr2 [ ] ; Function Call
