numbers, dates, currency or strings - The range validator in a web form helps check whether the value entered in the field falls between the minimum and maximum values allowed in that field. For example if the type of data accepted is of date type, then the rangevalidator checks whether the entered date falls within the given range. That means, month entered should be between 1 and 12, etc.

Design a finite automata from regular expression 10(0+11)0*1

Vilka [71]

<h3>What is a Finite automata?</h3>

A finite state machine (FSM) or finite state automaton (FSA), or simply a state machine, is a mathematical model of computation. It is an abstract machine that can be in exactly one of a finite number of states at any given time. The FSM may change from one state to another in response to some input; the change from one state to another is called a transition. An FSM is defined by a list of its states, its initial state, and the inputs that trigger each transition. Finite-state machines are of two types - deterministic finite-state machines and non-deterministic finite-state machines. A deterministic finite-state machine can be constructed equivalent to any non-deterministic machine.

With that being said, the DFA is equivalent to the expression 10(0+11)0*1 The expression that you've specified requires at least three 1 to be accepted. Breaking it down into parts.

<h3>Writting the automata:</h3>

S0: 1 => S1 ; 1

S0: 0 => error ; 0

S1: 0 => S1 ; 10+

S1: 0 => S2 ; 10(0

S2: 0 => S2

S2: 1 => S3

S3: 1 => S4

S4: 0 => S4

S4: 1 => S5

S5: 1 => S6 (final state)

Create the setStyles() function using the commands listed in the steps below. Christine wants one of five fancy style sheets to

jolli1 [7]

Answer:

Hi there! This can be implemented in a simple Python function which uses the "random" module to generate the number.

Explanation:

Using Python as the languge, we can write a the below code in a file called styles.py. The first line imports the randint function from the "random" module. The setStyles() function declares an array or 5 elements (here I have just used numbers but these could be string names of the stylesheets as well). Next, styleNum is assigned the random number and the associated stylesheet is selected from the array of stylesheets.

styles.py

from random import randint

def setStyles():

stylesheets = [1,2,3,4,5];

styleNum = randint(1,5);

stylesheet = stylesheets[styleNum];

print(stylesheet);

setStyles();
