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 "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.
Example
Input: 3 23 + 47 = machula 3247 + 5machula2 = 3749 machula13 + 75425 = 77038 Output: 23 + 47 = 70 3247 + 502 = 3749 1613 + 75425 = 77038
Note: int in C++/C/Java or longint in Pascal is enough.

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

There is only one "machula" in the test case. Example: input: 3 machula7 + 5 = 12 7 + 5machula = 12 7 + 5 = 1machula2 output: 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? Last edit: 2010-05-28 15:18:58 |

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. |

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. Last edit: 2009-09-28 16:07:58 |
