22

Whats wrong with my code i donā€™t understand. Its giving me a wrong answer !! Can someone help me ?

#include <iostream>

using namespace std;

int main() {
int t;
cin>>t;
while(t--)
{
    int n,m,k ;
    cin>>n>>m>>k;
    int i=0 ; // here i is the count of coins 
    while(true)
    {
        if(n<m)
            n+=1 ;
        else
            m+=1 ;
        i++ ;
        if(i==k)   // if number of coins are k then terminate
            break ;
    }
    cout<<abs(n-m)<<"\n";
}
return 0;
}
23

#include <bits/stdc++.h>
using namespace std;

int main() {
int T;
cin>>T;
int n,m,k,d;
for(int i=0;i<T;i++){
cin>>n>>m>>k;
d = abs(n-m) - k;
if(d<0){
cout<<(-d)%2<<endl;
}else{
cout<<d<<endl;
}
}

return 0;

}

why is this wrong??

24

#include<bits/stdc++.h>
using namespace std;
int main()
{
int t;
cin>>t;
while(tā€“)
{
int a,i,o,c;
cin>>a>>o>>c;
if(a==o)
{
if(c%2==0)

         cout<<"0"<<endl;

    else
        cout<<"1"<<endl;
    }

else
    {
         i=abs(a-o);
    if(i>=c)
        cout<<i-c<<endl;
    else
        if(c%2==0)
            cout<<"1"<<endl;
        else
            cout<<"0"<<endl;


    }

}
return 0;
}
Why is it wrong ?

25

DIid you got the reason ?

26

#include
using namespace std;

int main() {
int x,n=0,m=0,k=0;
cin>>x;
for(int i=0;i<x;i++){
cin>>n>>m>>k;
for(int j=0;j<k;j++){
if(n>m){
m=m+1;
}
else{
n=n+1;
}
}
if(n>m){
cout<<n-m<<endl;}
else{cout<<m-n<<endl;}

}
return 0;
}

Why wrong? please help

What is wrong with this code?? It is giving wrong answer.

int main(){
int t;
cin>>t;
while(t-- >0)
{
int diff,c,n,m,k;

while(k-- >0)
{
diff=diff-1;

Why my code is giving wrong answers?

same thing i am facing bro

38 
for _ in range(int(input())):
a,b,c=list(map(int,input().split()))
for i in range(c):
    if(a==b):
        break
    elif(a>b):
        b=b+1
        if(a==b):
            break
    else:
        a=a+1
        if(a==b):
            break
print(abs(a-b))

CHECK THIS U WILL GET IT I HOPEā€¦ IF BOTH R EQUAL U NEED NOT BUY MORE

I think there is some problem with Online judge

40

Online judge is wrong inthis question

41

one common thing others are missing is that we dont have to spend all of our gold coins
we minimise the difference and if difference is 0 and we still have coins left then we dont spend it
please if you can add this in editorial

42

first u spend 1coin,
itā€™ll bcome 3,3
again spend 1 coin
2,3
again 1
2,2
again 1
1,2

final will be 1 not 0
