ABSYS  AntiBlot System
Jimmy is a hardworking 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 nonempty 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.
Example
Input: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.

Can be easily solved using python3 without using any special functions, just keep in mind that there is a blank line after each line and python does not ignore blank lines and will input "" as your string. The only functions you will need is split,join,isdigit

just use stoi (for string)

cakewalk: simple addition and subtraction,i done using stoi(),as well as strstr() fntions

Wow..AC in first go...but it was one of those kind of problems where you what you have to do,its just the implementation where things get good. Nothing hard here, if you are good with strings,this is a piece of cake otherwise this is a must for you.

can be done without string also but use strings you'll get to learn a lot of string function.

No need to use substrings or any other string method. Simply use basic maths.
