Given a string, write a program to remove all the words with K length.
Input
The first line of input String A.
The second line of input an integer K.
Output
The output should contain a string after removing all the words whose length is equal to K.
Explanation
For example, string A is "Tea is good for you", k is 3 then output should be "is good."
Here words "Tea","for","you" length is equal to 3, so these words are removed from string.
You work in XYZ Corporation as a Data Analyst. Your corporation has told you to visualize the mtcars.csv dataset with various plots. Tasks to be performed:
Dataset Link 1. Plot a histogram for the column ‘wt’.
a. Map the ‘wt’ onto the x-axis.
b. Provide the x-axis label as ‘weight of the cars’.
c. Provide the y-axis label as ‘Count’
d. Set the number of bins as 30.
e. Set the title as ‘Histogram for the weight values
Write recursive functions (you are not allowed using for or while loops) to solve the following problems:
-Write a function that prints hello for 500 times
-x in power y ( )
-Geometric progression with common ratio r. For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3
