ABSYS - Anti-Blot System
Jimmy is a hard-working pupil in his second year at primary school. Recently he decided to convert all his notes into an electronic version. Sadly, he found that his math notes were full of ink blots.
He scanned the notes and sent them through his own OCR package
(yes, he coded it all by himself at the age of 8).
The OCR package replaced all ink blots by the string "
You are given Jimmy's notes, processed by the OCR. They contain simple math exercises, which were used to practice addition on positive integers. Your task is to recover the damaged part of the notes.
The first line of the input file contains an integer T specifying the number of test cases. Each test case is preceded by a blank line.
Each test case consists of exactly one line.
The line represents an equation of the form "
number + number = number",
number is a positive integer.
One part of the equation will be replaced by the string "
The string always covers a contiguous non-empty sequence of digits, possibly even an entire
number. You may assume that for each equation in the input there will be
exactly one way to fill in the missing digits.
For each test case, the output shall contain one line of the form
number + number = number". The line must represent the equation
from that test case with all missing digits filled in.
3 23 + 47 = machula 3247 + 5machula2 = 3749 machula13 + 75425 = 77038Output:
23 + 47 = 70 3247 + 502 = 3749 1613 + 75425 = 77038
Note: int in C++/C/Java or longint in Pascal is enough.

Python Simply ROCKSSS
INPUT INPUT INPUT and you are done (y) :D
trivial one, accepted in one go
Got right answer on ideone but getting WA everytime on spoj
Though ur IO Format is correct, it mat still show you error.
getting NZEC with python... works fine locally. Any clues ?
What's the use of blank line before input, such things usually go unnoticed and a cause of lot of time and WAs!! :\
why spoj show WA for space ??.what is the use of such space in programming
It was hard to meet the time limit by using java. You have to use all possible optimizations. Precompile your regexs, use BufferedReader instead of Scanner. Use PrintWriter.
I forgot removing freopen() functions and it gave me TLE, when I submitted the same code after removing freopen(), it was accepted. Can anybody tell me why it happened?
