Find Intersection
Have the function FindIntersection(strArr) read the array of strings stored in strArr which will contain 2 elements: the
first element will represent a list of comma-separated numbers sorted in ascending order, the second element will represent
a second list of comma-separated numbers (also sorted). Your goal is to return a comma-separated string containing the
numbers that occur in elements of strArr in sorted order. If there is no intersection, return the string false.
Examples
Input: ["1, 3, 4, 7, 13", "1, 2, 4, 13, 15"]
Output: 1,4,13
Input: ["1, 3, 9, 10, 17, 18", "1, 4, 9, 10"]
Output: 1,9,10

Python code:-
def FindIntersection(strArr):
val=[]
a=list(set(strArr[0].split(",")))
b=list(set(strArr[1].split(",")))
for i in range(len(a)):
a[i]=int(a[i])
for j in range(len(b)):
b[j]=int(b[j])
for i in range(len(a)):
for j in range(len(b)):
if(a[i]==b[j]):
val.append(a[i])
val=list(set(val))
val.sort()
if len(val) == 0:
return False
else:
return ",".join([str(i) for i in val])
# code goes here
# keep this function call here
print(FindIntersection(input()))

Have the function
ArrayChallenge
(strArr) read the
array of strings
stored in strazz which
will contain 2 strings
representing two
comma separated
lists of keypresses.
Your goal is to return
the string true if the
keypresses produce
the same printable
string and the string
false if they do not. A
keypress can be either
a printable character
or a backspace
represented by -B.
You can produce a
printable string from
such a string of
keypresses by having
backspaces erase one
preceding character.
