Each account is a list where the first value is a person’s name and the remaining values are email addresses. Two accounts belong to the same real person if they share at least one email address. The task is to merge every connected set of accounts and return one account per person, with the person’s name followed by that person’s emails in sorted order.

Quick facts

• Difficulty: MEDIUM
• Problem: Permutation in String
• Topics: Hash Table, Two Pointers, String, Sliding Window

Problem gist

Given two strings s1 and s2, the task is to decide whether s2 contains any contiguous substring that is a permutation of s1.

That means order inside the matching substring does not matter, but the character counts must match exactly. If s1 = "ab", then "ab" and "ba" are both valid windows. If s2 contains either one as a length-2 substring, the answer is True.

NVIDIA’s official Technical Blog published Enhancing Goodput in Large-Scale LLM Training with Nonuniform Tensor Parallelism, a July 6, 2026 post about keeping frontier-scale training jobs productive when some GPUs inside a tightly coupled training domain become temporarily unavailable.

The post is interesting because it treats training resilience as a parallelism problem, not only as a checkpointing or replacement problem. Large LLM jobs run across thousands of GPUs for long periods, and the useful measure is not raw peak throughput but Goodput: convergence-driving work completed over time. If one device in a tensor-parallel group slows down or drops out, the usual failure mode is disproportionate. A local hardware issue can stall a whole data-parallel replica, and because synchronous training waits on the slowest replica, that local issue can reduce throughput for the broader job.

Scientific American’s January 2026 article by Diana Kwon examines interoception, the brain’s ability to sense and interpret the body’s internal state. The article’s central argument is that mental health cannot be understood as a purely brain-bound problem. Heartbeats, breathing, hunger, fullness, pain, gut rhythms and immune signals are not background noise. They are part of the information stream from which emotion, fear, self-image and distress are built.
