Write a program entab that replaces strings of blanks by the minimum number of tabs and blanks to achieve the same spacing. Use the same tab stops as for detab. When either a tab or a single blank would suffice to reach a tab stop, which should be given preference?
Write a program detab that replaces tabs in the input with the proper number of blanks to space to the next tab stop. Assume a fixed set of tab stops, say every n columns. Should n be a variable or a symbolic parameter?
Finally, complete the following programming task on https://play.kotlinlang.org and submit your
link to Blackboard. The input should be a string declared at the top of the file.
We are given strings containing brackets of 4 types - round (), square [], curly {} and
angle ones. The goal is to check, whether brackets are in correct sequence. I.e. any
opening bracket should have closing bracket of the same type somewhere further by the
string, and bracket pairs should not overlap, though they could be nested:
here square and curly brackets are nested in the
(a+[b*c] - {d/3})
round ones
(a+[b*c) 17]
does not make sense
Input data will contain a test-case in form of a character sequence.
Answer should contain 1 (if bracket order is correct) or 0 (if incorrect) for each of test-
cases, separated by spaces.
Example:
input data:
(a+[b*c]-{d/3})
*
here square brackets overlap with round ones which
(a + [b c)
(((a * x) + [b] y) + c

For example, aaaba and bbaba are strings in the set, but aaaa and bbb are not. Provide a brief explanation of how your expression works.arrow_forwardModify the program below to implement exclusive-or (XOR) in Python. AsPython does not natively implement XOR, you will need to implement this by creating an expression using a combination of and, or, and not. Determine what this expression is, and put it in the code below (where “fill in your code here” is written).The starter code below includes the True/True and True/False cases. You should also include the False/True and False/False cases. As a reminder, XOR is only True if exactly one of the inputs is True. Other ways ofthinking about this is that it is True only if one input or the other input is True, but not both. Yet another way of thinking about this is that the result is only True when the inputs are different from each other.

Include appropriate tests for ‘special case’ conditions. Instead of “WritePixel” write to the screen the coordinates of the pixel that would be drawn. Your program must implement the algorithm given in class with modifications to handle the special cases. Different slope values: m = 0, m = 1, m = > 1, m = infinity (needs special test case) , m < 0 (swap x and y) The user should be able to enter coordinates and it should output the coordinates it takes to draw from the first point to the last pointarrow_forward

- 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.

Write a program that first gets a list of 5 integers from input. Then, get another value from the input, and output all integers less than or equal to that value. Ex: If the input is 50 60 140 200 75 100, the output is: 50 60 75 For coding simplicity, follow every output value by a space, including the last one. Then, output a newline.
