Question about the task Most frequent bytes
Java Core, Level 8, Lesson 3
Resolved
The task failed to pass testing with these messages: "Don't display the same byte several times." - "CodeGym security exception. You are performing a forbidden or potentially dangerous operation."What kind of forbidden or dangerous operation am I using??... And most importantly, what could be the basic bug in the program that is causing the test to fail? (The previous problem has been fixed: this program no longer contains static variables.)

Question about the task Most frequent bytes
Java Core, Level 8, Lesson 3
Resolved
The task failed to pass testing with this message: "Don't display the same byte several times."But when testing my program, it never repeated the same byte for me. Some test cases: INPUT FILE: OUTPUT: abccd 99 abcdAABCD 65 a b c d e 10 13 // these two are the bytes of the end of the lines, so also that's OK in my opinion. aaabbbc
