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.
running perfectly on my system..but showing compilation error (in c++) on spoj...
ac in one go!
running successfully on ideone but showing compilation error on submitting in c++Last edit: 2019-07-25 14:23:51
how to take the input as i am getting run time error(NZEC) in java everytime and the ideone says at java.util.Scanner.throwFor(Scanner.java:862)
take input like this
this problem will become if the input be like
if anyone is getting runtime error try taking two getline() ..... one for line and one for the string.
I did it AC in 1 go. I just stored 3 indexes, 1 for '+', '=', and 'm'. Then there are 3 cases that will decide where "machula" is located. Using this #knowledge, we can use stoi & substr to get the 2 ints and find the 3rd int using the value of the 1st 2 ints. Finally, we just make a new string with our new ints.Last edit: 2019-05-18 07:44:27
use stoi() and check char exist or not and get AC
