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 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).
