Activity life cycle Factorial and fabbonacci series lateiniti var vs lazy Var vs val

Question

Accepted Answer

Activity life cycle is a crucial concept in Android development. Factorial and Fibonacci series are common mathematical problems. lateinit var and lazy are used for initializing variables. Var and val are used for declaring variables.

Activity life cycle includes methods like onCreate, onStart, onResume, onPause, onStop, onDestroy.
Factorial is the product of all positive integers up to a given number. Example: 5! = 5*4*3*2*1 = 120.
Fibonacci series is a sequence where each number is the sum of the two preceding ones. Example: 0, 1, 1, 2, 3, 5, 8, 13, ...
lateinit var is used for non-nullable properties that are initialized in the constructor. lazy is used for properties that are initialized only when accessed for the first time.
Var is used for mutable variables, while val is used for immutable variables.
