A bicycle combination lock has four rings with numbers 0 through 9. Given the actual numbers and the combination to unlock, prin

t instructions to unlock the lock using the minimum number of twists. A "twist up" increases the number value of a ring, and a "twist down" decreases it. For example, if the actual number shown is 1729 and the desired combination is 5714, write your instructions in java like this:Ring 1: Twist up 4 timesRing 3: Twist down onceRing 4: Twist up or down 5 times

What is a neuromorphic chip?
Dominik [7]

Answer:

A neuromorphic computer is a machine comprising many simple processors / memory structures (e.g. neurons and synapses) communicating using simple messages (e.g. spikes). ... Neuromorphic computing systems excel at computing complex dynamics using a small set of computational primitives (neurons, synapses, spikes).

Explanation:

The structure of neuromorphic computers makes them much more efficient at training and running neural networks. They can run AI models at a faster speed than equivalent CPUs and GPUs while consuming less power. This is important since power consumption is already one of AI's essential challenges.
