Write a program that will read a line of text and output the number of words  in the line and the number of occurrences of each letter. Define a word to be  any string of letters that is delimited at each end by either whitespace, a period, a  comma, or the beginning or end of the line. You can assume that the input consists  entirely of letters, whitespace, commas, and periods. When outputting the number  of letters that occur in a line, be sure to count uppercase and lowercase versions of a  letter as the same letter. Output the letters in alphabetical order and list only those  letters that occur in the input line

A program in java

Write a complete Python program that opens a file called sample.txt for reading, and opens a file called out.txt for writing.

In python, write a code that allows the user to input two non-negative number sequences in increasing order (the numbers entered are always getting bigger, and no number repeats), both terminated by a -1. The size of each sequence can vary (maybe sequence - 1 has four numbers, and sequence - 2 has seven). The output of this code should be a third sequence that is a combination of both sequences 1 and 2 and is sorted in non-decreasing order.  Note: Non-decreasing order means there can be a repeated number in the third sequence (see example 1). A strictly increasing order sequence cannot have repeat numbers at all (see example 3). Remember, all input sequences must be in strictly increasing order! please do this using python, only using while loops. NO language of "break" or "len" please. Hint: we can use three separate lists to solve this code.

Programing C

Can you give me two ways to do it

In Java:  Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.

write a program that inserts parentheses, a space, and a dash into a string of 10 user-entered numbers to format it as a phone number. for example 5555555555 becomes (555) 555-5555. If the user does not enter exactly 10 digits, display an error message. continue to accept user input until the user enters 999 using string builder.
