Condition 1: A = A+B So, current value of A is 20+30 = 50 Condition 2: B = A-B Now, B = 50-30 = 20 We can see that we got the value of A in B Condition 3: A = A-B Finally, A = 50-20 = 30 A has the initial value of B. So, we just swapped the numbers. earfcn bandWebAug 12, 2024 · In order to simplify an equation, we have to look at it as an array of booleans. Taking for example an unsigned 8 bit integer: a = 0b10111001. Now becomes: a = {1, 0, 1, 1, 1, 0, 0, 1} Parsing. Once you can get your equations to just booleans, then you can apply the actual bitwise operators to simple 1s and 0s. css ch widthWebChef has two numbers N and M.
