Select the correct text in the passage. Which concept explained in the paragraph means that data remains hidden from the outside world?
All programs that we write in an OOP language consist of two elements: program code and data. Encapsulation is an object-oriented programming concept that binds together the data and the functions that manipulate the data. It keeps both the code and the data safe from outside interference and misuse. Binding properties and methods together provides controlled access to the data members and, therefore, ensures the security of the data.

Encapsulation is also closely linked with abstraction. Encapsulation prevents other programs from accessing the data directly, whereas abstraction refers to the feature of providing the functionality required, without disclosing the details of implementation.

Which part of the cpu accepts data?

Write a function balancechemical to balance chemical reactions by solving a linear set of equations. the inputs arguments are: reagents: symbols of reagents in string row array products: symbols of products in string row array elements: elements in the reaction in string row array elcmpreag: elemental composition of reactants in two dimensional numeric array elcmpprdcts: elemental composition of prducts in two dimensional numeric array hint: the first part of the problem is setting up the set of linear equations that should be solve. the second part of the problem is to find the integers from the solution. one way to do this is to mulitiply the rational basis for the nullspace by increasing larger integers until both the left-and right-side integers exist. for example, for the reaction that involves reacting with to produce and : reagents=["ch4", "o2"]; products =["co2", "h2o"]; elements =["c","h", "o"] elcmpreag=[1,4,0;
