For each pair, check if Bitwise XOR and the Bitwise AND of the pair is X and Y, respectively, or not.If found to be true, then print the Bitwise OR of that pair.. Time …
WebTo check a bit, shift the number n to the right, then bitwise AND it: bit = (number >> n) & 1U; That will put the value of the nth bit of number into the variable bit. Changing the nth bit to x. Setting the nth bit to either 1 or 0 can be achieved with the following on a 2's … WebMar 25, 2024 · Naive Approach: The simplest approach to solve this problem is to iterate up to the maximum of X and Y, say N, and generate all possible pairs of the first N natural …
