++I is a pre-increment operator that increments the value of I before using it, while I++ is a post-increment operator that increments the value of I after using it.

• ++I increments the value of I and then uses the updated value in the expression.

• I++ uses the current value of I in the expression and then increments it.

• Both operators can be used with variables, arrays, or pointers.

Time complexity measures the amount of time an algorithm takes to complete based on input size.

• Time complexity is expressed using Big O notation (e.g., O(n), O(log n)).

• O(1) indicates constant time, e.g., accessing an array element.

• O(n) indicates linear time, e.g., iterating through an array.

• O(n^2) indicates quadratic time, e.g., nested loops through an array.

• O(log n) indicates logarithmic time, e.g., binary search in a...read more

Gibbs free energy is a thermodynamic potential that measures the maximum amount of work that can be obtained from a system.

• It is denoted by the symbol G.

• It takes into account both the enthalpy and entropy of a system.

• A negative value of G indicates that a reaction is spontaneous.

• It is used to predict the feasibility of a chemical reaction.

• It is also used in the study of phase transitions and the stability of materials.

A class is a blueprint for creating objects that have similar attributes and methods.

• A class is a user-defined data type that encapsulates data and functions.

• It is a template for creating objects.

• It provides a way to organize and structure code.

• Objects are instances of a class.

• Classes can inherit properties and methods from other classes.

• Examples include String, Integer, and List in Java.
