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.
On same logic, I got TLE for JAVA but AC for C.Last edit: 2016-02-04 17:24:05
Don't think much, take each as separate string :)
Thanks Dushyant Singh for your advice.
Fix time limit, Java doesn't even load in 0.133s.
First go AC! Yo!
Lmao,Be Careful while printing !!!
what is the meaning of 'preceded by a blank line'?
almost all problems with best algorithm are getting TLE for java , i got correct answer in Ideaone but TLE here . For Java people it is annoying .
hhh.... cout<<'\n'; cost me 3 WA..... In general, it's an easy one, use strings not char because you don't want to get stuck with blank spaces.... In addition, use an array of 3 .... don't even look to machula.....if you are working with c++ isalpha is enough to make tab[i]=-1 and do testsLast edit: 2015-10-27 19:59:38
those using stoi() function, please use c++ 14, to avoid compile time errors;
