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.
got TLE in java for 3 times :(.
there are spaces in output.....be careful !!
pretty easy ac in one go
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
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.Last edit: 2015-09-06 06:12:53
Time limit not optimized for Java. :(
got AC in 3rd attempt, after "idone it".
