Swapping even and odd bits
SpletThe task is to swap all odd bits with even bits. For example, if the given number is 23 (00010111), it should be converted to 43 (00101011). Here, every even position bit is … Splet12. apr. 2024 · Rank 3 (ansh_shah) - C++ (g++ 5.4) Solution #include string oddToEven(string &num) { int n = num.size(); for(int i=0;i

Splet28. nov. 2024 · Use them to get the sum of odd indexed and even indexed elements for each subarray. Follow the steps mentioned below to implement the idea: Create two arrays (say odd[] and even[]). Iterate over the array from i = 0 to N-1: If i is odd put that element in odd[i]. Otherwise, put that in even[i]. Add odd[i-1] to odd[i] and even[i-1] to even[i].

Splet26. avg. 2024 · Adjacent elements are swapped as follows: 1, 2 -> 2, 1. 3, 4 -> 4, 3. Recommended: Please try your approach on {IDE} first, before moving on to the solution. Approach: The key observation in the problem is that there can be two cases for the arrays to swap the array elements: If the length of the array is even then we can easily Swap 2 ... Splet04. feb. 2024 · Write a program to swap odd and even bits in an integer with as few instructions as possible (e.g., bit 0 and bit 1 are swapped, bit 2 and bit 3 are swapped, and so on). Example1: Input: num = 2（0b10） Output 1 (0b01) Example2: Input: num = 3 Output: 3 Note: 0 <= num <= pow (2, 30) – 1 The result integer fits into 32-bit integer.
SpletIn this step, we are swapping the positions of the odd bits and the even bits. Let ans be the variable that stores the final result. Set ans as the Bitwise OR of oddPositionBits and evenPositionBits. Here, we are recombining the od bits and the even bits after swapping them. Return the variable ans. SpletThus to extract bits at even position we need a number which is all 1s at even position while 0s at at odd positions. Same analogy can be applied for odd positions. Once we have extracted the numbers we can shift number with even bits to left and second one to right.
Splet13. feb. 2024 · In JS you can write binary numbers with the 0b prefix. Eg 0b111 is 7. To swap even odd, you shift all bits to the left << 1 (same as * 2) and mask out & 0b10101010 the odd bits. The for the even you shift all bits to the right >> 1 similar to /2, mask out the even bits & 0b101010101 and add or or the result of the previous shift.
