The program is to find a mathematical series, where we need to accept the value of n and m. n is the base number and m is the number of times till which the series run.
Examples:
Input : 2 + 22 + 222 + 2222 + 22222 Output : 24690 Input : 12 + 1212 + 121212 Output : 122436
We first convert the numbers into string format and concatenate them regularly. Later, we convert them back to integer and add them upto mth term. as shown in the following program.
# Python program to sum the given series # Returns sum of n + nn + nnn + .... (m times) def Series(n, m): # Converting the number to string str_n = str(n) # Initializing result as number and string sums = n sum_str = str(n) # Adding remaining terms for i in range(1, m): # Concatenating the string making n, nn, nnn... sum_str = sum_str + str_n # Before adding converting back to integer sums = sums + int(sum_str) return sums # Driver Code n = 2m = 5total = Series(n, m) print(total) |
Output:
24690
