ABSYS - Anti-Blot System

no tags 

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 "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 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.

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 = 77038

Output:
23 + 47 = 70
3247 + 502 = 3749
1613 + 75425 = 77038

Note: int in C++/C/Java or longint in Pascal is enough.

I think there is NO other types if test cases , so a write code only consider test case given in the same Order.

What i did is take all input like cin>>input1 for first number and cin>>input2 for "+" and so on.
And then convert string to number(not all only number inputs) , stoi is working in my code so i write own made fun to string to int (check web if u dont know) and then just do the maths.

For INPUTS:-
Like this cin>>op1>>plus>>op2>>eq>>op3;
int v1 = convert(op1); //convert is my own fun ret = ret*10 + (str[i]-'0') i.e. converting into number then multi with 10

CONVERT op1,op2 and op3 to numbers

WARNING : BLANK LINES
use getline() cautiously.
in c++

use try and except in python

Use stoi() {use try and catch} , make sure your cpp compiler is version cpp-11 or above its an easy fix,check online , also stoi(5machula2) gives 5 so make sure to cover this case also.

running perfectly on my system..but showing compilation error (in c++) on spoj...

ac in one go!
using stringstream and stoi functions

running successfully on ideone but showing compilation error on submitting in c++

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)

at java.util.Scanner.next(Scanner.java:1485)

at java.util.Scanner.nextInt(Scanner.java:2117)

at java.util.Scanner.nextInt(Scanner.java:2076)

at Main.main(Main.java:15)
this error every time.i have also taken a sc.nextLine() as for the blank line.

sanket17: 2019-07-08 14:37:08

take input like this
cin >> a >> b >> c >> d >> e;
now just check a,c,e string
almost constant time

this problem will become if the input be like
-23 + 47 = machula
means also contain negative numbers
