Create a program that determines and displays the number of unique characters in a string entered by the user. For example, Hello NITS Students! has 15 unique characters, while zzzz has only one unique character. python only with instructions
Here is the indexOf method that I wrote: public static int indexOf(char[] arr, char ch) { if(arr == null || arr.length == 0) { return -1; } for (int i = 0; i < arr.length; i++) { if(arr[i] == ch) { return i; } } return -1; ...
In Java Only can use class String length charAt class StringBuilder length charAt append toString class Character any method Create the following methods nthWord takes an int and a String as input and returns a String: The input int represents a number n that is assumed to be positive, and the output string contains every nth word of the input string, starting with the first word, separated by a single space. {\em For this method, a word is defined to...
If string s has 3 characters and string t has 7 characters, what size does string s need to be at a minimum?
please answer question
(5 points) Below is the skeleton for a simplified StringBuilder class as done in the Closed Lab this semester. As in the lab, the class has an ArrayList of Character to hold the individual characters of the StringBuilder object. Write the instance method indexOf as given below that returns the index of the first occurrence of the character c in the SimplestringBuilder. If there is no index for that character (i.e. the character is not in the...
The ____ method returns the length of a String. a. size() b. length() c. getLength() d. getSize()
1. What is output by the following code? String s0 = "Java"; int i1 = s0.indexOf('a'); int i2 = s0.indexOf('a', i1); int i3 = s0.indexOf('a', i1 + 1); System.out.print(i1 + " " + i2 + " " + i3); 2. What is output by the following code? String s1 = "Java"; String s2 = ""; for (int i = 0; i < s1.length(); i++) { s2 += s1; } System.out.print(s2);
A string is a sequence of characters. Write a C++ program by creating a user-defined string class that performs the following functions: String comparison String concatenation Returning the length of the string Reversing a string backward Reversing a string backward
Exercise 1 • Examine ShoppingCart.java. – Perform the following: – Use the indexOf method to get the index for the space character (" ") within custName. Assign it to spaceIdx. – Use the substring method and spaceIdx to get the first name portion of custName. Assign it to firstName and print firstName. public class ShoppingCart { public static void main (String[] args){ String custName = "Steve Smith"; String firstName; int spaceIdx; // Get the...
In C++, create a recursive bool function which determines if a string is symmetrical or not. A symmetrical string can be read the same front to back (ex. kayak). Function Blueprint --------------------- bool isSymmetrical(string s) if (s is the empty string or s is of length 1) return true else if (s's first and last characters are the same letter) return isSymmetrical (s minus its first and last characters) else return false
