Chapter 2, Problem 23RE
Suppose you are given a string str and two positions i and j, where i comes before j. The following pseudocode describes how to swap two letters in a word.
We are given a string str and two positions i and j. (i comes before j)
Set first to the substring from the start of the string to the last position before i.
Set middle to the substring from positions i + 1 to j - 1.
Set last to the substring from position j + 1 to the end of the string.
Concatenate the following five strings: first, the string containing just the character at position j, middle, the string containing just the character at position i, and last.
Check this pseudocode, using the string "Gateway" and positions 2 and 4. Draw a diagram of the string that is being computed, similar to Figure 5.

Q. Hi andre
Write a Java program to check if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward, ignoring spaces, punctuation, and capitalization.
For example, "racecar" and "Madam" are palindromes, while "hello" and "Java" are not.
Your program should take a string as input and return true if it's a palindrome, and false otherwise.
Ok.
Please help me with Python
Suppose that I have a string (input)
a = '0,200, 15,550, 25,977, 99,1489\n'
I want the output of this string to be:
b = [0, 200, 15, 550, 25, 977, 99, 1489]
c = [(0, 200), (15, 550), (25, 977), (99, 1489)]
d = ['0', '200', '15', '550', '25', '977', '99', '1489']
How can I do this in Python for each case?
Python please:
Write a program with an input that is a string and a number. Output the first character in the string and then the character that is the number's distance away from the previous character, repeating for the remainder of the string as long as the string is longer than the increment number. Your output wording should match the below examples.
For example, if the input is
hello 2
the output is
h l o
If the string contains fewer characters than the input number, as in
cat 4
the output is
The integer can't be higher than the string length.
For coding simplicity, output a space after every character, including the last.

When determining whether an alphanumeric string is a palindrome, we often ignore spaces, punctuation and case in the string (e.g. "A man, a plan, a canal --Panama!" is also considered a palindrome). Write a complete C program to read a string, echo it to the screen, determine whether it is a palindrome, and write a message indicating whether it is or isn't. Your main function should prompt for the string, read the string, print it, call the clean function (to remove all spaces, punctuation, and turn uppercase letters into lowercase letters), print the new string, then call the reverse function (to place the characters into reverse order) and print the new string resulting. In the final step, you will compare the result of the reverse function with the original string and print a message if the string is a palindrome or not. The clean…arrow_forward
- When we say arithmetic expression, we mean a kind of expression you can type in a very basic desk calculator. That is, neither variables nor brackets are allowed. It contains only numbers and four arithmetic operators, +, -, *, and /. The following are some examples of arithmetic expression: Any number string with or without signs - e.g. 3, -1, +10, 3.14, -0.70 and 099. Number strings mixed with arithmetic operators - e.g. 3+5, -1+2*3, 7/10-0.7, and -1.4-+8.2. An example of FA diagram for recognising a non-negative integer is given below. You may use it as a start point. You need to add a few more states and transitions to handle numbers with decimal point and signs (e.g. -5, +2, 0.21, -32.6, +99.05, but not the form 1.0E-3).

- You're interested in looking at trending Twitter hashtags, but you notice that people aren't very consistent with how they use them. Specifically, the capitalisation and punctuation in hashtags is inconsistent. You decide to write a program to read in tweets, normalise any hashtags present, and print out a tally of frequencies. Hashtags should only include words starting with #. All punctuation should be removed from the end of a hashtag, and the letters should be converted to lowercase. For instance, #Python! should be normalised to #python, and #Today_I_Learned... should be #today_i_learned. Your program should work like this. The tally of hashtags can be printed out in any order.

Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B and C = 2 D, E and F = 3 G, H and I = 4 J, K and L = 5 M, N and O = 6 P, Q, R and S = 7 T, U and V = 8 W, X, Y and Z = 9 Write a program that asks the user to enter a 10-character number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663. After displaying the translated telephone number, ask the user if they’d like to enter another number.
