For this Question: Given an integer S represented as a string, the task is to get the sum of all possible sub-strings of this string.The only line of input contains a single integers S represented as a string.

1 <= len(S) <= 1000000Print the required sum modulo (10^9 + 7)Sample Input 1:
1234

Sample Output 1:
1670

Explanation:
Sum = 1 + 2 + 3 + 4 + 12 + 23 + 34 + 123 + 234 + 1234
 = 1670

Sample Input 2:
421

Sample Output 2:
491

Explanation:
Sum = 4 + 2 + 1 + 42 + 21 + 421
 = 491, I have written this Solution Code: s = input().strip()

ln = len(s)

prev = int(s[0])
sm = prev
for i in range(1,ln):
	nxt = (i+1)*int(s[i]) + 10 * prev
	sm += nxt%1000000007
	prev = nxt%1000000007

print(sm%1000000007), In this Programming Language: Python, Now tell me if this Code is compilable or not?
