WebNov 14, 2024 · Time Complexity: O(log(m) + log(n)), We can improve the time complexity for the above problem to O(log(n)) by using binary shift operators. Auxiliary Space: O(1) Better Approach: We will binary shift the number M to left by the number of bits in n.. Example: M=4, N=5. bin(N) = 101 which has binary representation three. We will left binary shift M … WebMar 27, 2024 · The idea is to use bitset container in C++. Using bitset, we can precalculate the existence all the subset sums in an array in O (n) and answer subsequent queries in just O (1). We basically use an array of bits bit [] to represent the …

WebApr 9, 2024 · Method#1: We follow the following logic to check binary of number is Palindrome or not: Find number of bits in x using sizeof () operator. Initialize left and right positions as 1 and n respectively. Do following while left ‘l’ is smaller than right ‘r’. If bit at position ‘l’ is not same as bit at position ‘r’, then return false. WebMar 24, 2024 · Simply put, the task is to find the total number of 1’s(set bits) in the integer. Example 1 Input Given Integer (N) = 15 Output Count of set bits in 15 = 4 Explanation The binary representation of 15 looks like this: 15 = 23+ 22+ 21+ 20= 8 + 4 + 2 + 1 = 15 So, the total number of set bits, i.e., the total number of bits with value one is 4. ts tech sun india pvt. limited
