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.

if all constraints are in int how WA by taking character array of 15 and AC by taking size as 20

took half of my day but finally ac ,playing with strings

"Each test case is preceded by a blank line. " Don't get fooled by this line. :-P There can be many blank lines before input. Like this

23 + 47 = machula

Python, my baby. AC in 1 go. Not that this is such a great problem to cherish.

you (JAVA people) might hit Time Limit Exceeded if you don't care about the way you are reading the input.

Time limit not optimized for Java. :(

got AC in 3rd attempt, after "idone it".
care about input format .

suhas: 2015-08-16 19:29:12

used getline twice to compensate the blank line. :P

nice one.. :)

this question is all about int and str.
Take each thing separately rather than one string.costed me 7WA throughout 1 month.
took separate ,AC in one shot. Hell.
