+""" Problem Statement (Digit Fifth Power ): https://projecteuler.net/problem=30
+
+Surprisingly there are only three numbers that can be written as the sum of fourth powers of their digits:
+
+1634 = 1^4 + 6^4 + 3^4 + 4^4
+8208 = 8^4 + 2^4 + 0^4 + 8^4
+9474 = 9^4 + 4^4 + 7^4 + 4^4
+As 1 = 1^4 is not a sum it is not included.
+
+The sum of these numbers is 1634 + 8208 + 9474 = 19316.
+
+Find the sum of all the numbers that can be written as the sum of fifth powers of their digits.
+ 
+(9^5)=59,049‬
+59049*7=4,13,343 (which is only 6 digit number )
+So, number greater than 9,99,999 are rejected
+and also 59049*3=1,77,147 (which exceeds the criteria of number being 3 digit)
+So, n>999
+and hence a bound between (1000,1000000)
