Answer 1

EXPLANATION:

Step 2: call the function with different parameters to check the output

SOLUTION:

##define the function that takes two parameters
def findWordCrossIndex(horizontalWord,verticalWord):
##iterate through each letter in horizontalWord and check for matching in verticalWord
##if matching found to return the index
for i in range(len(horizontalWord)):
if (horizontalWord[i] in verticalWord):
return i
##if any value is returned it will exit from the program by returning that index if not the remaining statements will be\
##executed i.e -1 is returned if not found
##if any value is not returned then only this will execute
return -1

##call the function for debugging
print(findWordCrossIndex("hello","abcd"))

OUTPUT:

-1 since no matching found
