Looking at their binary representations, let k be the highest bit where they differ. For example, if A = 28 = 11100_2 and B = 26 = 11010_2, we’d have k =2, because the first time the binary representations differ is at 2^2 = 4.

WebMar 15, 2024 · XOR is a logical operator that works on bits. Let’s denote it by ^ . If the two bits it takes as input are the same, the result is 0, otherwise it is 1 . This implements an exclusive or operation, i.e. exactly one argument has to be 1 for the final result to be 1 . We can show this using a truth table: x. y. x ^ y. 0. WebChef wants to assign a binary value ( 0 or 1) to every node of the tree.

WebJun 20, 2024 · For n > 4, you can always follow the below strategy to get a good sequence: find the first index that has non-zero value. If you are not able to find, then the output is -1 Lets name the index as nzi. Now you can take another index nzi2 such that it is nzi-2 or nzi+2. If nzi is odd then fill all even indices with arr [nzi] ^ arr [nzi2] WebCodechef is a programming contest platform.
