(i) Write a program in C to receive the values of rainfall depth and display the
number of days with light rain ( 7.6 mm) from the
record in Table 1.
(ii) Rewrite the program in (c)(i) to identify and display the day with the lowest value
of rainfall depth, the day with the highest value of rainfall depth and the average
value of rainfall depth for the past 7 days.
(3) (a) Consider the following interaction with Python:
x= [1,2,34 ,5 ,6 , np.nan]
y= (10,i,2,5, 'Missing',6.3)
z= [0.1, 1.2 , np.nan , 4,5.1,0.5]
df1=DataFrame ({'col1':Series (z),'co12':Series (y),
'col3': Series (x)}).
df1.index= ['a','b','c', 'd','e','f']
Replace the NaN value in coll with -9, the Missing value in col2 with -99, and the NaN
value in col3 with -999 with relevant functions. Name as dfl_replaced
(b) Consider the following interaction with Python:
df2=DataFrame (np. array ( [[1, np.nan ,3, 8], [np.nan , 2,3,5] ,
[10,2,3, np.nan], [10,2,3 , np.nan],
[10,2,3,11]]))
df2.columns = ['one', 'two', three', four ']
df2. index= ['a','b','c
'd','e']
Remove the rows that have nan values from df2 and name as df2_row. Remove the
columns that have nan values from df2 and name as df2_column. Use relevant
functions.

The union of two ordered lists (Sequential linear list)[the solution
introduction: The first video of in 3.1, 35:00-43:00]
[Problem description]
Give the union of two ordered lists. The maximal number of elements in an
inputted set is 30.
[Basic requirements]
1) Use sequential linear list.
2) The result list should also be ordered.
[Example]
Problem: Give the union of the ordered lists (3,4,9,100,103) and
(7,9,43,53,102,105).
What you need to show in the terminal(the back part is outputted by you
and the blue part is inputted by the user, i.e., teacher):
Please input the first ordered list: (3,4,9,100,103)Please input the second ordered list: (7,9,43,53,102,105)
The union is:
(3,4,7,9,9,43,53,100,102,103,105)
