# Volume Control: VOLCONTROL

Volume Control CodeChef Solution in C, C++, Java, and Python 3

Chef is watching TV. The current volume of the TV is XX. Pressing the `volume up` button of the TV remote increases the volume by 11 while pressing the `volume down` button decreases the volume by 11. Chef wants to change the volume from XX to YY. Find the minimum number of button presses required to do so.

### Input Format

• The first line contains a single integer TT – the number of test cases. Then the test cases follow.
• The first and only line of each test case contains two integers XX and YY – the initial volume and final volume of the TV.

### Output Format

For each test case, output the minimum number of times Chef has to press a button to change the volume from XX to YY.

• 1≤T≤100
• 1≤X,Y≤100

### Sample Input 1

``````2
50 54
12 10``````

### Sample Output 1

``````4
2``````

## Volume Control CodeChef Solution in C

``````int T;
scanf("%d",&T);
while(T--)
{
int x,y;
scanf("%d%d",&x,&y);
if(x < y)
{

printf("%d\n",y-x);
}
else
{
printf("%d\n",x-y);
}
}
return 0;
}

## Volume Control CodeChef Solution in C++ 17

``````// your code goes here
int t;
cin>>t;
for(int i=0; i < t; i++){
int x, y;
cin>>x>>y;
if((x>y) || (x==y)){
cout << (x-y) << endl;
}
else{
cout << (y-x) << endl;
}

}
return 0;
}

## Volume Control CodeChef Solution in Python 3

``````t = int(input())
for i in range(t):
l=list(map(int,input().split()))
ans = {True:"YES", False:"NO"}
print(max(l)-min(l))``````
