How Interview Coder Helps
Get real-time assistance for Partition Array to Minimize XOR problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
nums = [1,2,3], k = 21The optimal partition is [1] and [2, 3]. XOR of the first subarray is 1. XOR of the second subarray is 2 XOR 3 = 1. The maximum XOR among the subarrays is 1, which is the minimum possible.
nums = [2,3,3,2], k = 32The optimal partition is [2], [3, 3], and [2]. XOR of the first subarray is 2. XOR of the second subarray is 3 XOR 3 = 0. XOR of the third subarray is 2. The maximum XOR among the subarrays is 2, which is the minimum possible.
nums = [1,1,2,3,1], k = 20The optimal partition is [1, 1] and [2, 3, 1]. XOR of the first subarray is 1 XOR 1 = 0. XOR of the second subarray is 2 XOR 3 XOR 1 = 0. The maximum XOR among the subarrays is 0, which is the minimum possible.
