Current Implementation

Mode: Normal

trim_end(file)

judge!(AC, b"1\r\n\r\n\r\n", b"1  ");

for each line, trim_end(line)

judge!(AC, b"1 \n", b"1");

for each line, check spaces between non-space chars

judge!(PE, b"1 3\n", b"1         3\n");

Mode: Strict

User file must have the same bytes with std file.

There is no "PE" in this mode.
