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.

Interesting one. Beware of blank lines in between test cases, it cost me a couple of attempts. |

python3 input().split()---> made it easy |

Difficulty depends on language of choice Last edit: 2017-05-31 16:00:11 |

nice problem ac in one go: HINT: use of substr(),<sstream>,find(),no use of cin.ignore() as such |

Very Good Problem Hint : Break into individual strings ! AC in 1 GO |

make sure about the blank lines above every test case..!!overall its a easy one |

use stringstream to convert string to int also study about cin.ignore() to solve the problem Last edit: 2017-03-07 14:29:17 |

just keep in mind the spaces between numbers and blank lines between test cases. caused me errors.. |
