Write a program to print the product of a non-empty list of integers, i.e. the result of multiplying those numbers with each other. The answer box contains a simplification of Pattern 2.6 (Aggregate) as comments, to get you started. Write the corresponding code beneath each comment. Use variable names appropriate to the problem at hand instead of the generic names used by the pattern. The first step has been done for you. For example: Input Result [5] 5 [5, 2] 10 [2, 5, 1] 10 [2, -5, 3] -30

Write a function squares in Python that accepts a 2-dimensional list of integers or a list of ranges as an input, and that returns the count of all the integers that are perfect squares. A perfect square is an integer that is the square of another integer. 9 is a perfect square because 9 is equal to 3 squared. don't worry about the ranges, if you write your code in the obvious way, it will also work for ranges. Sample usage: >> squares( [[1,2,3],[4,5],[6,7,8,9]]) # 1,4,9 are perfect squares3
I have a program that asks for queries. It is based on a CSV file with three columns for a person's name, city, and height. The print statement for City_list gives it a blank. The problem I'm running into is that if I insert a city that isn't in the CSV file, it ends and doesn't transition to other cities. When I do put in the city that is in the list, it prints out the indexes from the file. How can this be revised to ignore off-list cities and work with in-list cities?

Your Task: Remove any word that does not start with a capital letter. For instance, for the input text of "Hello, 2022 world!", we should get "Hello, 2022 !". Notes: As in the previous question, you can safely assume that the set of characters that will be used will be only among the following: alphabetical characters [A-Za-z] (upper and lower case English letters), numerics [0-9] (digits), the space character [ ], and the following 6 punctuations: [.,!?;:]. You can define a word as follows: starts with a letter [A-Za-z], then proceeds with alphanumeric characters [A-Za-z0-9] until hits a non alphanumeric character (so a space character or a punctuation). However, if for simplicity, you take each word to be allowed to start with numeric characters too, that is fine as well (your outputs will be considered as valid). So for instance, the words like 2way, 4door, etc or even numbers like 2022 are also valid words. STARTER CODE: .data buffer_for_input_string: .space 100…
Write a program in C that create a 3-by-5 array. All elements in the array are random integer numbers between 1 and 100. Then, put all elements of the two-dimensional array into a one-dimensional array. Finally, calculate the mean value and the median value of 1-D array. Print out the 2-D array, original 1-D array, sorted 1-D array, and the mean value and the median value of 1-D array.
Python please... Implement a function printIndex() that takes a list as a parameter, prompts the user to enter a whole number n, and prints the element in position Index[n]. If the list is empty ([]) or n is not a valid index into the list, the function will not print anything. Be careful to do the correct thing with negative indices. You should assume that the user will enter a whole number when prompted, and the function will crash if the user does not enter an integer. The function should not change the list passed as a parameter. Hint: Just because this involves a list does not mean that you need a loop to solve the problem. Think carefully about the right construct to use here. The following shows the function template, and several examples runs of the function (you must show all the examples with these values in your submission): Template def printIndex(lst): replace with your docstring newList = lst # ________________________ elementNum =…

In Java: When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain less than 20 integers. Ex: If the input is: 5 30 50 10 70 65 the output is: 20 40 0 60 55 For coding simplicity, follow every output value by a space, even the last one. Your program must define and call a method:public static int getMinimumInt(int[] listInts, int listSize) import java.util.Scanner; public class LabProgram {/* Define your method here */ public static void main(String[] args) {/* Type your code here. */}}
Write a program in python which will read an integer k from standard input. Use the list function and the range function to print a list of the even integers from -10 up to k (inclusive). Notice the form of the output is a list. NOTE: If k is less than -10, your range command should automatically produce an empty sequence, resulting in an empty list being printed. See the provided examples. For example: Input Result 5 [-10, -8, -6, -4, -2, 0, 2, 4] -11 [] 11 [-10, -8, -6, -4, -2, 0, 2, 4, 6, 8, 10] 2 [-10, -8, -6, -4, -2, 0, 2]
An acronym is a word formed from the initial letters of words in a set phrase. Write a program whose input is a phrase and whose output is an acronym of the input. If a word begins with a lower case letter, don't include that letter in the acronym. Assume there will be at least one upper case letter in the input. in python please.

I need to write a Java ArrayList program called Search.java that counts the names of people that were interviewed from a standard input stream. The program reads people's names from the standard input stream and from time to time prints a sorted portion of the list of names. All the names in the input are given in the order in which they were found and interviewed. You can imagine a unique timestamp associated with each interview. The names are not necessarily unique (many of the people have the same name). Interspersed in the standard input stream are queries that begin with the question mark character. Queries ask for an alphabetical list of names to be printed to the standard output stream. The list depends only on the names up to that point in the input stream and does include any people's names that appear in the input stream after the query. The list does not contain all the names of the previous interviews, but only a selection of them. A query provides the names of two people,…
A user is going to enter numbers one at a time, entering 'q' when finished. Put the numbers in a list, sort it in numerical order, and print out the list. Then print out the middle element of the list. (If the list has an even number of elements, print the one just after the middle.) Remember that a list 1st of numbers can be sorted numerically by calling 1st.sort(), and can be printed with print(1st). You can assume that every entry is either a valid integer or is the letter 'q'. Examples: If the input is 4 3 6 7 3 q The output is [3, 3, 4, 6, 7] 4 If input is 4 3 6 7 3 2 q The output is [2, 3, 3, 4, 6, 7] 4
