Jack and Rose are lovers. They play a digital game every day. The rules are as follows:

[1] Jack randomly selects a number x from the range [a, B ].

[2] Rose randomly selects a number x from the range [c, d ].

[3] If (x + y) mod p = m, they will go out to the movies.

[4] Otherwise, study in the library

Given integers a, B, c, d, p, m, they want to know the probability of going out to a movie.

 

Code:

 

# Include <iostream>

# Include <cstdio>

# Include <cmath>

# Include <algorithm>

# Include <climits>

 

Using namespace std;

Int main (){

Int t;

Cin> t;

While (t --){

Int a, B, c, d, p, m;

Int count = 0;

Int res;

Cin> a> B> c> d> p> m;

For (int x = a; x <= B; x ++ ){

For (int y = c; y <= d; y ++ ){

If (x + y) % p = m ){

Count ++;

}

}

}

Res = (B-a + 1) * (d-c + 1 ));

If (count = 0 ){

Cout <0 <"/" <1 <endl;

}

Else {

For (int I = 2; I <= count; I ++)

If (count % I = 0 & res % I = 0 ){

Count/= I;

Res/= I;

I --;

}

Cout <count <"/" <res <endl;

}

}

Return 0;
