Input :n = 5
Output : 2.70833

Input :n = 7
Output : 2.71806




# Python code to find smallest K-digit  
# number divisible by X
  
def sumOfSeries(num):
      
    # Computing MAX
    res = 0
    fact = 1
      
    for i in range(1, num+1):
        fact *= i
        res = res + (i/ fact)
          
    return res
      
  
n = 5
print("Sum: ", sumOfSeries(n))
