Given the coordinates of each crocodile and the distance so James could jump, you must tell him whether or not he can ES Cape.Input Specification:Each input file contains the one test case. Each case starts with a line containing the positive integersN(≤100), the number of crocodiles, andd, the maximum distance that James could jump. Thennnlines follow, each Containing The (x, y) location of a Crocodile. Note that no crocodiles is staying at the same position. Output

To match the letter "|", you can use \| or include it in a character class, such as [|].

The Cron daemon can execute shell scripts at a specified time. In fact, it is the same as the bat file for Job Scheduling in windows.
# Crontab regularly executes commands (this is my main learning)
# At only once
# The batch system is scheduled for batch processing when the attachment is allowed
During system initialization, the cron daemon will check the crontab file and at record files, and immediately send the changes to the cron daemon for execution.
# Ps-ef | grep cron

Crontab introduction crontab commands are common in Unix and Unix-like operating systems and are used to set periodically executed commands. This command reads commands from the standard input device and stores them in the crontab file for later reading and execution. The word is derived from the Greek chronos (QP? ν ο ?), The original intention is time. Generally, the commands stored in crontab are activated by the Daemon, and crond is often run in the background. check whether a scheduled job
