- My problem is the column in the photo (column [7]) includes a "$". So it would be read as a string. The other picture is my line of code that needs to be changed to accumulate the "$". My question is can someone rewrite this line/ write another line of code that could work with this column so my code can run?I have to add the following solution to a code. The chapter is focused on strings and string manipulation including slicing, searching, splitting, and case conversions. Can you help me with this? 1. Input a date in numeric format from the user e.g. mm/dd/yy. 2. Examine the month entered by the user. If it is larger than 12 or smaller than 1 issue an error message and ask for input again. 3. Perform similar validation tests for the date and year. Year must be 2013. (Any other year is invalid) In addition, the year must only be two digits long. 4. Once all input has been validated, output the string in long date format. Thus a string that was input as 06/01/15 will be output as June 1, 2015.Hi can you a sendscreenshot showing that you are writing and running the code in Matlab/Octave Thanks
- 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. Tweet: #Python is #AWESOME!Tweet: This is #So_much_fun #awesomeTweet: #python 1#awesome 2#so_much_fun 1Using Javascript and HTML: An interesting application of computers is drawing graphs and bar charts (sometimes called histograms). Write a script that reads five numbers between 1 and 30. For each number read, output HTML5 text that displays a line containing the same number of adjacent asterisks. For example, if your program reads the number 5, it should out HTML5 test that displays *****.Can you write a new code in Java language with the values I sent you, just like this output? There are two files named group1.txt and group2.txt that contain course information and grades of each student for each class. I will calculate each course average for each group and show in simple bar graph. Use "*" and "#"characters for group1 and group2, respectively. I will see the number -999 at the end of each line in the input files. This value is used for line termination and you can use it to verify that you have arrived at the end of the line. The averages of each group should also be calculated and printed at the end of the file.

Fixed lines start with an area code neclosed in parenthesis. The area codes vary in length but always begin with 0. Mobile numbers have no parenthesis, but have a space in the middle of the number to help readability. the prefix of a mobile number is its first four digits and they always tart with 7,8, or 9. Telemarkets numbers have no parenthese or space, but they start with the area code 140. The return string for outgoingCallsFromBangalore should be all the area codes in lexicographic order with no duplicates.You have N boxes in Samosas, where each box is a cube. To pack the box, you need to use a rubber band (pseudo-circular, elastic band) by placing it next to the box (4 faces of a cube). The rubber band A (R1, R2) has an initial radius of R1 and can be expanded in size up to R2 without breaking. You can pack a cubic box of side length L using a 4 * L round rubber band (see Notes for clarity). Given the M-band bands and their first radius and the main radius, we need to match (provide) some rubber bands and boxes. The box needs at least one rubber band to pack and of course, each rubber band can be used to pack at least one box. Find the maximum number of boxes we can pack. Answer this in java programming language. Input Output 2 1 4 10 20 34 55 4 714 7 21 14 21 7 35
- P1 P2 P3 P4 A pentagonal number is one that corresponds to dots arranged into a pentagon. Above are the first four pentagonal numbers and their pentagons. The pentagonal number PN has sides made of N dots. When you count the dots for a pentagonal number, include the dots for the inner pentagons. So to figure out how many dots PN has, find out how many P(N-1) has and add the dots for the new sides of size N. P1 = 1, P2 = 5, P3 = 12, P4 = 22 Figure out a recursive formula for PN and then write a function that implements it. That is, implement pentagonal() using recursion. pentagonal(1) -> 1 pentagonal(2) -> 5 pentagonal(3) -> 12In console.log() function in JavaScript a newline character is automatically printed at the end.
