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.
nice problem ac in one go:
Very Good Problem
AC in first go...
make sure about the blank lines above every test case..!!overall its a easy one

use stringstream to convert string to int
just keep in mind the spaces between numbers and blank lines between test cases. caused me errors..
The problem can be extended to new SPOJ problems, more difficult. Its the hint for enthusiastsLast edit: 2017-02-21 10:48:13
Beware the empty lines between each formula. Cost me the first AC...
