When I use the Intelli IDE to try to solve this chess board problem, I saw this message: Connected to the target VM, address: '127.0.0.1:53542', transport: 'socket' My solution to this task passed the validation on the web, BUT when I try to run it on the Intelli IDE, it cannot print out anything, and even in debug mode, it shows only the above message. Anyone know what is wrong with the IDE? thanks for helping.
