URI Problem 2746 Solution Viruses - URI Online Judge Solution

URI Online Judge Solution 2746 Viruses Using PostgreSQL Query Language.

Viruses are evolving, but new research has proven that by switching some proteins the vaccine becomes unbeatable. The protein H1(Hemagglutinin) when replaced by the X protein (Xenomorphina) has interesting effects against almost every viral disease. Some conspiracists say that after the vaccine’s discovery some strange 3 meters tall creatures were found in the surroundings of the laboratories, but this is clearly a lie.

Therefore, you must replace every string “H1”( Hemagglutinin ) by 'X' ( Xenomorphina ).

URI Problem 1179 Solution Array Fill IV - URI Online Judge Solution

URI Online Judge Solution 1179 Array Fill IV Using C, Python Programming Language. In this problem you need to read 15 numbers and must put them into two different arrays: par if the number is even or impar if this number is odd. But the size of each of the two arrrays is only 5 positions. So every time you fill one of two arrays, you must print the entire array to be able to use it again for the next numbers that are read.
