Answer:
The program in Python is as follows
def Paths(row,col):
if row ==0 or col==0:
return 1
return (Paths(row-1, col) + Paths(row, col-1))
row = int(input("Row: "))
col = int(input("Column: "))
print("Paths: ", Paths(row,col))
Explanation:
This defines the function
def Paths(row,col):
If row or column is 0, the function returns 1
<em> if row ==0 or col==0:
</em>
<em> return 1
</em>
This calls the function recursively, as long as row and col are greater than 1
<em> return (Paths(row-1, col) + Paths(row, col-1))</em>
The main begins here
This prompts the user for rows
row = int(input("Row: "))
This prompts the user for columns
col = int(input("Column: "))
This calls the Paths function and prints the number of paths
print("Paths: ", Paths(row,col))
