Speed Limit Test Solution Codechef

Alice is driving from her home to her office which is A kilometers away and will take her X hours to reach.
Bob is driving from his home to his office which is B kilometers away and will take him Y hours to reach.

Determine who is driving faster, else, if they are both driving at the same speed print EQUAL.

Input Format

  • The first line will contain T, the number of test cases. Then the test cases follow.
  • Each test case consists of a single line of input, containing four integers A,X,B, and Y, the distances and and the times taken by Alice and Bob respectively.

Output Format

  • For each test case, if Alice is faster, print ALICE. Else if Bob is faster, print BOB. If both are equal, print EQUAL.
  • You may print each character of the string in uppercase or lowercase (for example, the strings equal, equAL, EquAl, and EQUAL will all be treated as identical).

Constraints

  • 1≤T≤1000
  • 1≤A,X,B,Y≤1000

Sample Input 1
3
20 6 20 5
10 3 20 6
9 1 1 1

Sample Output 1
Bob
Equal
Alice

Explanation

  • Test case 1: Since Bob travels the distance between his office and house in 5 hours, whereas Alice travels the same distance of 20 kms in 6 hours, BOB is faster.
  • Test case 2: Since Alice travels the distance of 10 km between her office and house in 3 hours and Bob travels a distance of 20 km in 6 hours, they have equal speeds.
  • Test case 3: Since Alice travels the distance of 9 km between her office and house in 1 hour and Bob travels only a distance of 1 km in the same time, ALICE is faster.

SOLUTION

Program: Speed Limit Test Solution in Python

for _ in range(int(input())):
    a,x,b,y = map(int, input().split())
    if a/x > b/y :
        print('Alice')
    elif a/x == b/y :
        print('Equal')
    else :
        print('Bob')

	    cin>>a>>b>>x>>y;
	    if(a/x > b/y)
	    {
	        cout<<"Alice"<<endl;
	    }
	    else if(a/x < b/y)
	    {
	        cout<<"Bob"<<endl;
	    }
	    else
	        cout<<"Equal"<<endl;
	    
	}
	
	return 0;
