URI Online Judge Solution | 1035 Selection Test 1

Hints: Don’t forget to think that A is even so we have to use a%2==0 that’s it

 

URI Online Judge Solution | 1020 Age in Days

Solution:
Just think simple
if we take age input then if we want year then we have to divide the age with year,then if we want to find out the age in month as 1 year is 365 and 30 days of 12 months then we have to remainder and resultant value divided by 30 and at last for days of age we have to use remainder of 356 days and remainder of 30 respectively as 365 days for 1 year and 30 days for 1 months

 

URI Online Judge Solution| 1019 Time Conversion

Input format=integer
Output format=hours:minutes:seconds
Solution:
1 minute =60 second
1hour = 60minute

1min = 60 second
60 min = 60*60=3600 seconds

3600 second=1hour
1 second=1/3600 hour
556 second=556*1/3600 hour

3600 second =60 minute
1 second = 60/3600 minute
556 second = 60/3600 * 556 minute
Here, in this case in finding minute we also have to use remainder because it is the portionate part of hour so the formula will be n%3600*60

556 second = 556 % 60 because second is the part of seconds and we want to find out the seconds so in this case we have to use remainder

 

URI Online Judge Solution | 1017 Fuel spent

Solution:
Here is the given hint is
“the amount of liters of fuel spent on a trip, using a car that does 12 Km/L”
and “This way you can get distance”
And I have to take input spent 10 hours and average velocity 85km/h so the formula for how many litre fuel spent in this path is c=85*10/12 We actually got this by using unitary method 🙂

 

URI Online Judge Solution| 1014 Consumption

Solution:Though car consumption means http://www.racq.com.au/cars-and-driving/cars/owning-and-maintaining-a-car/fuel-saving-tips/measuring-fuel-consumption that desribe here’s broadly

The following formula is used to calculate fuel consumption in litres / 100kms, the most commonly used measure of fuel consumption.


Example a car uses 65 litres to travel 500km

(65 X 100) / 500 = 13

(Litres used X 100) / km travelled = Litres per 100km.


 

but in the problem it is saying that medium of the car consumption with 3 digit after the decimal point so we have just divided the integer x and float y and got the answer. 🙂

 

URI Online Judge Solution | 1013 The Greatest

Solution:
I have took help from net.And after taking a look I understood what to do actually.

Here for each test case I have to use this formula

After using MaiorAB that means in portugese and in english by google translating i have find it is maximum or larger or more in AB

URI Online Judge Solution| 1011 Sphere

Problem Link: https://www.urionlinejudge.com.br/judge/en/problems/view/1011
Solution:

I first tried to do with float but it was not giving me correct answer for 3rd test case so i have searched in the net for solution the i have seen that i have to use double as double is for 8 byte where as float was for 4 byte

So i have used float and result is correct upto all test cases 🙂
