So from the start of the call to the end of the call, minus the time the CPU switches to another context, it can be multi-threaded. The phenomenon is that a short Python CPU usage of more than 100% can be observed in such a situation.If you execute multiple contexts,
maximum satisfying condition f (n) = N. If you can estimate this n, then just let N go from N to 0, each check for f (n) = n, and the first number that satisfies the condition is the integer we require.
Therefore, the problem is transformed into how to prove that the upper bound n does exist and estimates the upper bound N.
There is an upper bound to the number that satisfies the condition f (n) = n
First of all, we use a similar mathematical inductive method to infer this problem. It's easy

1 fixed capacitor DetectionA is a small capacitor below 10 PF. Because the capacity of the fixed capacitor below 10 PF is too small, the multimeter can only be used for measurement to check whether there is leakage, internal short circuit or breakdown. During measurement, you can use a multimeter r×10k block, and use two pen to connect two pins of the capacitor separately. The resistance value should be infinite. If the measured resistance value (poin

RABBITMQ:RABBITMQ is a Message Queuing product implemented with Erlang by the AQMP protocol, which implements the broker schema, which can be queued on the central node before it is sent to the client. This feature makes RABBITMQ easy to use and deploy, and is suitable for many scenarios such as routing, load balancing, or message persistence.
