Hello Programmers In this post, you will know how to solve the Buggy Calculator Codechef Solution.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.
Problem
Trans bought a calculator at creatnx’s store. Unfortunately, it is fake. It has many bugs. One of them is adding two numbers without carrying. Example expression: 12 + 9 will have result 11 in his calculator. Given an expression in the form a + b, please output result from that calculator.
Input
The first line contains an integer T denote the number of test cases. Each test case contains two integers a, b in a single line.
Output
Each test case, print answer in a single line.
Constraints
- 1 ≤ T ≤ 100
- 1 ≤ a, b ≤ 109
Subtasks:
- Subtask #1 (30 points): 1 ≤ a, b ≤ 9
- Subtask #2 (70 points): original constrains
Sample Input 1
2 12 9 25 25
Sample Output 1
11 40
Buggy Calculator CodeChef Solutions in JAVA
import java.util.*; import java.lang.*; import java.io.*; class Codechef { public static void main (String[] args) throws java.lang.Exception { // your code goes here Scanner sc = new Scanner(System.in); int tcases = sc.nextInt(); while(tcases-->0) { int a = sc.nextInt(); int b = sc.nextInt(); int sum=0; int count=0; while(a>0 || b>0) { int dig = ((a%10)+(b%10))%10; sum = dig*(int)Math.pow(10,count)+sum; a=a/10; b=b/10; count++; } System.out.println(sum); } } }
Buggy Calculator CodeChef Solutions in CPP
#include <iostream> using namespace std; int main() { int t; cin>>t; while(t--){ int a,b,r1,r2,res,f=1,sum=0; cin>>a>>b; while(a>0 || b>0) { r1=a%10; r2=b%10; res=(r1+r2)%10; sum+=res*f; f*=10; a=a/10; b=b/10; } cout<<sum<<endl; } return 0; }
Buggy Calculator CodeChef Solutions in Python
import math def xsum(a,b): multiplier=1 bit_sum=0 res=0 while(a or b): bit_sum=((a%10) +(b%10)) bit_sum=bit_sum%10 res=(bit_sum*multiplier)+res a=math.floor(a/10) b=math.floor(b/10) multiplier=multiplier*10 return res for i in range(int(input())): a,b=map(int,input().split()) print(xsum(a,b))
