Do not end with newline.Write a program that gets a list of integers from input, and outputs non-negative integers in ascending order (lowest to highest).

Do not end with newline. simple pythonImplement the vacuum cleaning agent function in Python/Java for the scenario described below: Consider two-dimensional Boolean array of size m x n (m and n can each be equal to 4) where m is the number of rows, and n is the number of columns. Obtain numerical positive integer values for m and n as inputs from the user. Generate random numbers and scale them down to either a “0” or a “1” according to whether they represent “Clean” or “Dirty”, respectively. After filling the array with 0s or 1s, start at some random array position indicating the initial position of the vacuum cleaner. First check if at that current position, there is the presence of a “Dirt” or not determined by whether 0 or 1 is filled in at that initial position of the vacuum cleaner. If there is a “Dirt”, clean it, and if there is no “Dirt” do a No-operation. After this is done, generate random numbers modulo 4 to obtain random numbers 0, 1, 2, 3 indicating whether to take a left, right, up or down correspondingly. If…
- Write a program in Python that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Ex: If the input is: 5 50 60 140 200 75 100 the output is: 50 60 75 The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.Write a python program: In the first century AD, Nicomachus suggested in his book entitled Introduction Arithmetica that “Cubical numbers can always be represented as the sum of successive odd numbers.” For example, 1^3= 1 = 1 2^3 = 8 = 3 + 5 3^3 = 27 = 7 + 9 + 11 4^3 = 64 = 13 + 15 + 17 + 19 Input N and output the successive odd integers whose sum is i^3 for all i in the set { 1,2,..,N } .Write regular expressions for the following languages. By “word”, we mean an alphabetic string separated from other words by whitespace, any relevant punctuation, line breaks, and so forth. (a) The set of all alphabetic strings;(b) The set of all lower case alphabetic strings ending with a letter b;(c) The set of all strings with two consecutive repeated words (e.g., “Humbert Humbert” and “the the” but not “the bug” or “the big bug”);(d) All strings that start at the beginning of the line with an integer and that end at the end of the line with a word;(e) All strings that have both the word grotto and the word raven in them (but not, e.g., words like grottos that merely contain the word grotto);
- Write a program to build a calculator. Instead of a typical calculator which reads in-order expressions and evaluates them, build a calculator that takes in numbers and assigns the operations to yield the highest value expression. The current operations on the calculator only handle pairs of parentheses, and the operators for addition, subtraction, multiplication, and division. The calculator can rearrange the numbers if it helps find the optimal value. For example, the list:4.0 5.0 3.0 2.0 1.0using the calculator should find the optimal expression yielding the maximum value to be:4.0 * 5.0 * 3.0 * (2.0 + 1.0) = 180Input from the keyboard a list of up to 10 floating-point values from-100000.0to100000.0. Output to the screen a single floating-point value rounded to two decimal places representing the highest value expression that the calculator could create by inserting the symbols( ) + - * /into the given expression. Assume at least one number in the list and only the operators listed…write a java program using stacks: 1. For a given expression in the form of a string, find if there exist any redundant brackets or not. It is given that the expression contains only rounded brackets or parenthesis and the input expression will always be balanced. A pair of the brackets is said to be redundant when a sub-expression is surrounded by unnecessary or needless brackets. Sample Input 1: (a+b)+c Sample Output 1: false Explanation: Since there are no needless brackets, hence, the output must be 'false'. Sample Input 2: ((a+b)) Sample Output 2: true Explanation” The expression can be reduced to (a+b). Hence the expression has redundant brackets and the output will be 'true'.Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain less than 20 integers. Ex: If the input is: 5 50 60 140 200 75 100 the output is: 50,60,75, The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75. For coding simplicity, follow every output value by a comma, including the last one. Such functionality is common on sites like Amazon, where a user can filter results.
