ABSYS - Anti-Blot System

no tags 

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 "machula".

Problem specification

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.

Input specification

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", where each number is a positive integer. One part of the equation will be replaced by the string "machula". 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.

Output specification

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.



23 + 47 = machula

3247 + 5machula2 = 3749

machula13 + 75425 = 77038
23 + 47 = 70
3247 + 502 = 3749
1613 + 75425 = 77038

Note: int in C++/C/Java or longint in Pascal is enough.

I keep getting WA :(

since there's only 1 answer, it's ok to replace the whole word if there's "machula", right?

also, is there such input as
1 + 0machula = 2
that would output
1 + 01 = 2 ?

the string with machula can be quite long, so take care.

There is only one "machula" in the test case. Example:

machula7 + 5 = 12
7 + 5machula = 12
7 + 5 = 1machula2

7 + 5 = 12
7 + 5 = 12
7 + 5 = 12

@.::NEO::. :read the problem carefully .there will be a blank line after each test case .you should chek your code for blank line

The empty lines between test cases are significant. Poor decision considering the input states "Each test case consists of exactly one line"

should I assume there is one and only one 'machula' in each test case?

where should I place the input and output file?should I take the filenames from command line?i am doing the program in c

> Should the blank spaces between operators...
One space between each operator and number is enough.

Seshadri R: 2009-09-27 12:23:00

Should the blank spaces between operators and digits in the output should match those in the input?

Re: You'd better do that. The blank at the start or the end of the line and empty lines don't matter.
