LS = ["HIMALAYA", "NILGIRI", "ALASKA", "ALPS"]
D = {}
for S in LS:
if len(S) % 4 == 0:
D[S] = len(S)
for K in D:
print(K, D[K], sep = "#")
Output:
HIMALAYA#8
ALPS#4
Explanation:
The list LS contains the strings: ["HIMALAYA", "NILGIRI", "ALASKA", "ALPS"].
The code iterates through each string in LS. If the length of the string is divisible by 4, it adds the string as a key and its length as the value in dictionary D.
The dictionary after execution becomes: {"HIMALAYA": 8, "ALPS": 4}.
Finally, the dictionary keys and values are printed with a # separator.
HIMALAYA#8
ALPS#4
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
