Re: 227 - Puzzle

Code: Select all

I won.
The ending condition is for sure:
fgets(line, some number, stdin);
if (line[0] == 'Z' && strlen(line) == 2) stop processing
make sure to read input line by line. it's imperative.

Re: 10905 - Children's Game

This problem is horribly written and doesn't include bounds on the input. Read and process everything as strings. The problem might talk about everything being integers, such as In next lines there are N positive integers. So you read and process items as int32s, then int64s... But the problem never...

Re: New language: Python ?

hopefully anyone that searches the forums for python code submission format can find this:

I've submitted an AC solution with this format

Code: Select all

#!/usr/bin/python3

def main():
	*code*
	
if __name__ == "__main__":
	main()

Re: 424 - Integer Inquiry

input: 1a 0 output 29 The java solution would throw a runtime error.. also: input -2 -1 0 gives *3 when the java solution should give -3 input: 000 0 gives nothing, when the java AC solution would report 0. I know the problem statement says: The input will consist of at most 100 lines of text, each ...

Re: 424 - Integer Inquiry

The udebug code for this problem has to be wrong.
The java AC solution reads big integers until the number equals 0 and keeps the running sum.

Try input: 1000 4000 1100 3000 2000 1900 2002 1900 2001 1899 You code is correct if you remove the debug info it prints: 4 1 2 3 5 However if you change to left.weight < right.weight it incorrectly prints: 4 1 2 4 5 shouldn't 4 1 2 3 4 be an acceptable answer too?

Re: 459 - Graph Connectivity

I'm gonna throw my code up here because I'm not exactly sure what I'm doing wrong for this problem. I'm new to trying to solve graph problems (that weren't implicit graphs modeled as ascii maps for like floodfill problems), so I'm trying to model this problem input as an adjacency matrix... and I th...

Re: 11821 - High-Precision Number

omfg. Java BigDecimal method stripTrailingZeros only works some of the time (actually it seems to only work for zeros after the decimal point). Hence the stupidly looking use of compareTo.

brianfry713 -> how are you so good at test cases?

I'm wondering how you've developed the strategy to determine critical test cases so that I may share the knowledge with others.
