#Here is code to number of ways of distributing N identical objects in R distinct groups and the other steps required.
 def ncr ( n , r ) :
	ans = 1
	for i in range ( 1 , r + 1 ) :
		ans *= ( n - r + i )
		ans //= i
	return ans
def NoOfDistributions ( N , R ) :
	return ncr ( N + R - 1 , R - 1 )
N = 4
R = 3
print ( NoOfDistributions ( N , R ) )
