Given the head of a singly linked list, group all the nodes with odd indices together followed by the nodes with even indices, and return the reordered list. The first node is considered odd, and the second node is even, and so on. Note that the relative order inside both the even and odd groups should remain as it was in the input. You must solve the problem in O(1) extra space complexity and O(n) time complexity. For example: Input: head = [1,2,3,4,5] Output: [1,3,5,2,4] Input: head = [2,1,3,5,6,4,7] Output: [2,3,6,7,1,5,4]

You're troubleshooting a mission-critical server (cannot be rebooted) that is experiencing severe lag. You only have terminal access. Describe your debugging process, including specific commands and tools you'd use to diagnose the issue. For example, would you start by checking CPU usage, memory consumption, or disk I/O? What commands would you use to identify the most resource-intensive processes? How would you investigate potential network bottlenecks or file system issues? Be as detailed as possible in outlining your approach to pinpointing the cause of the lag and suggesting potential solutions, keeping in mind that a reboot is not an option.
