Just a small comment: I'm actually one of those who doesn't use file reads in the code. Instead I use command like:
time cat "$INPUT_FILE" | ./"$EXEC_FILE" "debug" or > time cat "$INPUT_FILE" | ./"$EXEC_FILE" > "$OUTPUT_FILE" switching between 2 depending on whether I'm debugging or not. It gives me flexibility of running the code independently from the input file name. Even more, I usually work on one problem at a time and the input file to process is the last modified "*.in" file in the folder, so I added some magic to determine which input file to process: INPUT_FILE=`ls -t -1 | grep "in$" | head -1` This way, I never actually enter input file manually at all – I either download new input or edit the sample input file. P.S. This may not be the most efficient bash usage, as you don't need cat in first example (you can redirect stdin instead) or grep in second (you can specify mask in ls command), but it was written fast to save some time for coding, instead of beautifying the bash code :) On 16 March 2016 at 19:20, 'Pablo Heiber' via Google Code Jam < [email protected]> wrote: > Hi, > > In a nutshell, I guess most people are not copy/pasting the input but > redirecting stdin to read from a file. > > You can redirect files to the standard input by using " < filename" after > your execution line.
