This count value is the log2 (x). 9) Checking if given 32 bit integer is power of 2. WebApr 13, 2024 · Left Shift (<<) It is a binary operator that takes two numbers, left shifts the bits of the first operand, and the second operand decides the number of places to shift. In other words, left-shifting an integer “ a ” with an integer “ b ” denoted as ‘ (a<
WebFeb 16, 2024 · Add each number once and multiply the sum by 3, we will get thrice the sum of each element of the array. Store it as thrice_sum. Subtract the sum of the whole array from the thrice_sum and divide the result by 2. The number we get is the required number (which appears once in the array).

Using Bitwise AND operator: The idea is to check whether the last bit of the number is set or not. If last bit is set then the number is odd, otherwise even. As we know bitwise AND Operation of the Number by 1 will be 1, If it is odd because the last bit will be already set. Otherwise, it will give 0 as output. flowpodcast bolsonaroWebDec 13, 2024 · Method 2 (Using Bitwise XOR) The bitwise XOR operator can be used to swap two variables. The XOR of two numbers x and y returns a number that has all the bits as 1 wherever bits of x and y differ. For example, XOR of 10 (In Binary 1010) and 5 (In Binary 0101) is 1111, and XOR of 7 (0111) and 5 (0101) is (0010).
