Using just the at, length, and substr string methods and the + (concatenate) operator, write a function that accepts a string s, a start position p, and a length l, and returns a subset of s with the characters starting at position p for a length of l removed. Don’t forget that strings start at position 0. Thus (“abcdefghijk”, 2, 4) returns “abghijk”

With simply the at, length, and substr string methods and the + (concatenate) operator, construct a function that accepts a string s, a start position p, and a length l and returns a subset of s without the characters starting at position p. Strings begin at 0. (“abcdefghijk”, 2, 4) yields “abghijk”.
Write a function that counts the occurrences of a word in a string. Thefunction should return an integer. Do not assume that just one space separates words and a string can contain punctuation. Write the function sothat it works with either a String argument or a StringBuilder object.
Write a regular expression that defines strings that have an even (but nonzero) number of "a" characters followed by an odd number of "b" characters. For example, aab, aabbb, aaaab, and aaaabbb should all match the regular expression.
Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1 below. Expression Effect strVar.at(index) Returns the element at the position specified by index strVar[index] Returns the element at the position specified by index strVar.append(n, ch) Appends n copies of ch to strVar, where ch is a char variable or a char constant strVar.append(str) Appends str to strVar strVar.clear() Deletes all the characters in strVar strVar.compare(str) Returns 1 if strVar > str returns 0 if strVar == str; returns −1 if strVar < str…

Task 2: Implement the function Searchingstrings that allow to search a sub-string in a given string and display the: First occurrence, Last occurrence, First occurrence from a given index and Last occurrence from a given index. You can use the following String methods: string. IndexOf(searchvalue, start) return the position of the first occurrence of specified character(s) in a string. string.lastIndexOf(searchvalue, start) return the position of the last occurrence of specified character(s) in a string. You can use the following string to test your solution: var letters = "abcdefghijklmnopqrstuvwxyzabcdefghijklm"; Write the code in a separate.js and separate.html file.
Write a function that counts the occurrences of a specified non-overlapping string s2 in another string s1 using the following header:def count(s1, s2):For example, count("system error, syntax error", "error") returns 2. Write a test program that prompts the user to enter two strings and displays thenumber of occurrences of the second string in the first string.
Draw NFA that accepts the set of strings over {a, b} such that there should be at least one substring which starts and ends with a b and the number of symbols between these two b’s is divisible by 4. Example: abababaaaababab, babbaa (since 0 is divisible by 4), ababababbaa.l
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.
