1.Write a program to find largest number among three number. Also, design flowchart of the program. 

2. Write a C Program to Calculate the Power of a Number. [Hint Use math.h library and pow() function ]

Write a regular expression for the following languages, over sigma=(a,b) All strings that do not end with aa.All strings that contain an even number of b’s. All strings which do not contain the substring ba.

Construct NFA for the regular Expression R=(a+b) ∗abb

The Pythagorean theorem states that the sun of the squares of the sides of a right triangle is equal to the square of the hypotenuse. Given two positive integers, m and n, where m>n, a Pythagorean triple can be generated by the following formulas:

Side 1= m2 - n2

Side 2 = 2mn

Hypotenuse = m2 + n2

Write a program in visual basics that reads in values for m and n and prints the values of the Pythagorean triple generated by these formulas

Product of values in the Sub-array(s)

Given an array

nestedArray of arrays, write a JS program to multiply the values in the sub-array if at least one of its values is even else return zero.

Quick Tip

You can use array methods map(), some() and reduce().

Input

• The input will be a single line containing an array nestedArray

Output

• The output should be a single line containing an array

Constraints

• Each value in the array must be a number

Sample Input 1

[ [ 12, 1, 2, 4, 1 ], [ 18, 20, 30, 45 ], [ 49, 11, 13, 21 ] ]

Sample Output 1

[ 96, 486000, 0 ]

Sample Input 2

[ [ 0, 1 ], [ 1, 3, 4 ] ]

Sample Output 2

[ 0, 12 ]

i want code in between write code here

"use strict";

process.stdin.resume();

process.stdin.setEncoding("utf-8");

let inputString = "";

let currentLine = 0;

process.stdin.on("data", (inputStdin) => {

 inputString += inputStdin;

});

process.stdin.on("end", (_) => {

 inputString = inputString.trim().split("\n").map((str) => str.trim());

 main();

});

function readLine() {

 return inputString[currentLine++];

}

/* Please do not modify anything above this line */

function main() {

 const nestedArray = JSON.parse(readLine());

 /* Write your code here */

}

Split and Replace

Given three strings

inputString, separator and replaceString as inputs. Write a JS program to split the

inputString with the given separator and replace strings in the resultant array with the replaceString whose length is greater than 7.

Quick Tip

• You can use the string method split()
• You can use the array method map()

Input

• The first line of input contains a string inputString
• The second line of input contains a string separator
• The third line of input contains a string replaceString

Output

• The output should be a single line containing the strings separated by a space

String Starts or Ends with given String

Given an array

stringsArray of strings, and startString, endString as inputs, write a JS program to filter the strings in stringsArray starting with startString or ending with endString.

Quick Tip

You can use the array method filter() and logical operator OR ( || ).

Input

• The first line of input contains a string stringsArray
• The second line of input contains a string startString
• The third line of input contains a number endString

Output

• The output should be a single line containing an array of filtered strings

Sample Input 1

['teacher', 'friend', 'cricket', 'farmer', 'rose', 'talent', 'trainer']

t

r

Sample Output 1

[ 'teacher', 'farmer', 'talent', 'trainer' ]

Sample Input 2

['dream', 'player', 'read', 'write', 'trend']

p

d

Sample Output 2

[ 'player', 'read', 'trend' ]

Create a program using a one-dimensional array that accepts five input values from the keyboard. Then it should also accept a number to search. This number is to be searched if it is among the five input values. If it is found, display the message “Searched number is found!”, otherwise display “Search number is lost!”.
