WebFeb 27, 2024 · 2. 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. how can diet affect a child\u0027s development

WebJun 3, 2024 · Approach: Since every number can be expressed as sum of powers of 2, the task is to print every i when i th bit is set in the binary representation of N. Illustration: (29) 10 = (11101) 2. Thus, in 29, {0, 2, 3, 4} are the indices of the set bits. 2 0 + 2 2 + 2 3 + 2 4. = 1 + 4 + 8 + 16. = 29. WebFeb 28, 2024 · The idea is to use bitwise <<, & and ~ operators. Using the expression “~(1 << (k – 1))“, we get a number that has all bits set, except the kth bit.
