XOR Equal CodeChef Solution - CodingBroz

WebWith that equation we can calculate a AND b. Now to count the number you want, we look at each bits of a XOR b and a AND b one-by-one and multiply all possibilities. (Let me write a[i] for the i-th bit of a) If a[i] XOR b[i] = 0 and a[i] AND b[i] = 0, then a[i] = b[i] = 0. Only one possibility for this bit. WebYour goal is to have as many equal integers as possible in the array. To achieve this goal, you can do the following operation: Choose an index i (1 ≤ i ≤ N) and set Ai = Ai ⊕ X, where ⊕ denotes the bitwise xor operation. Find the maximum number of equal integers you can have in the final array and the minimum number of operations to ...

WebMar 15, 2024 · Most programming languages implement ^ as a bitwise operator, meaning XOR is individually applied to each bit in a string of bits (e.g. a byte). For example: 0011 ^ 0101 = 0110 since 0 ^ 0 = 0 0 ^ 1 = 1 1 ^ 0 = 1 1 ^ 1 = 0 Because of this, we can apply XOR to anything, not just booleans. Deducing Some Useful Properties Web(A_1 + x) \oplus (A_2 + x) \oplus \dots \oplus (A_N + x) = 0 (A1 +x)⊕(A2 +x)⊕⋯⊕(AN +x)=0 where \oplus ⊕ denotes the bitwise XOR operation. If no such x x exists, print -1 −1. Note: The input of this problem is large, so use fast input/output methods. Input Format First line of the input contains a single integer T T, the number of test cases.
