b) String manipulation is common in programming. It is used for example to do input validations, or simply change the nature of the String. Trace the following PHP script outputs. $str = "Need to learn PHP to ease my FYP next semester!"; (i) echo strlen ($str); (ii) echo substr($str, 2, 7); (iii) echo strtolower ($str); (iv) echo str_word_count ($str); (v) echo str_repeat ($str, 2); c) Analyse FIVE (5) types of String method as stated in Question 3(b).

Make a php web page that prompts the user for a phone number. The web page should display a message whether it is a valid phone number entry or not. Write a function that uses regular expression that flexibly matches a U.S. phone number whether or not it has parentheses around the area code and has its parts seperate by spaces, hyphens, or peroids. The regular expression should match phone numbers written like this: (718) 498-1043(718) 498 1043718 498 1043718 498-1043718-498-1043718.498.1043
IN PHP Create a function that takes a number and return a string with the number in expanded notation (AKA expanded form). See the resources tab for details on expanded notation. Examples expand (13) → "10+ 3" expand (86) - ➡ "80 + 6" expand (17000000) →"10000000 + 7000000" expand(5325) ➡ "5000 + 300 + 20+ 5"
IN JAVA SCRIPT Programming Create a function that takes a string as an argument and returns true if each letter in the string is surrounded by a plus sign. Return false otherwise. Examples plusSign("+f+d+c+#+f+") → true plusSign("+d+=3=+s+") → true plusSign("f++d+g+8+") false plusSign("+s+7+fg+r+8+") → false

DescriptionA researcher is analyzing DNA. A DNA can be represented as a string composed of the characters A, G, C, or T.One day, researchers found a strange DNA, which is Smooth Repeated DNA. The DNA is represented by a string that has infinite length. The string has a repeating pattern, i.e. the DNA string 0 is repeated an infinite number of times. For example, if0 = "????", then = "???????????? . . . ".According to researchers, a DNA is said to be special if it contains substrings . Determine whetheris a substring of . Squad FormatA line containing the two strings 0 and . Output FormatA line that determines whether it is a substring of . Issue “YES” ifis a substring of . Output “NO” otherwise.

Q1: Write a C# program that reads the information list of n students (name, age, List of 10 degrees and average) in a single string for each student in the following form "[Name: D₁, D2,.....D10];>"; and compute the average from the degrees list. Then, print the information (all fields) of any student has the following properties: Name doesn't start with "Ba" and ends with "ky" The Age less than 45 and greater than 30 Successful in 7 degrees and the Average doesn't exceed 70 Note: Both Structure and LINQ Principles must be used in the above program
public static String pancakeScramble(String text) This nifty little problem is taken from the excellent Wolfram Challenges problem site where you can also see examples of what the result should be for various arguments. Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string.This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is,str = new StringBuilder(str).reverse().toString(); Here's the tester it must pass: @Test public void testPancakeScramble() throws IOException {// Explicit test casesassertEquals("", P2J3.pancakeScramble(""));assertEquals("alu",…

Maybe one day the Java strings will come with the reverse method built in, just like the string data types of all sensible…
Hi, my name is Alex. This is an assignment that is due tonight at 11:59 pm. This assignment was supposed to be due next Friday, but my teacher changed the date at the last minute. I tried to get help from other sites and none have been able to help me. You are my last hope. String as Singly Linked List In many programming languages, the String class is typically implemented as an array of characters. Some other languages, such as Haskell, Erlang, and a few other functional programming languages, however, implement strings as Singly Linked List (SLL) of characters. Compared with the array implementations, the SLL ones are very easy for pattern matching because of the recursive structure of linked list. Let’s don’t worry about recursion in this assignment. In this assignment, you will implement a SLLString class using SLL. Your SLLString class will include the following members: SLLString(); //Default constructor SLLString(const string& other); //copy constructor taking a C++…
PHP Write a matchIPAddress function Write a function matchIPAddress($str) that takes a string representing an IP address as a parameter. The function should return true if the IP address is valid, and false if it is not. An IP address consists of a series of 4 numbers on the range 0-255 separated by dots (e.g. 192.168.0.1). Use regular expressions with capture groups and some additional validation in your solution (e.g. preg_match).]
in coral language Write a program that first gets a list of 5 integers from input. Then, get another value from the input, and output all integers less than or equal to that value. Ex: If the input is 50 60 140 200 75 100, the output is: 50 60 75 For coding simplicity, follow every output value by a space, including the last one. Then, output a newline. Such functionality is common on sites like Amazon, where a user can filter results.
