Write a program that takes an input string, and returns which characters are consecutively repeated the most times. If there are multiple characters, return them in sort order.
- "aaddddffffaa" will return
[d, f] - "cat dog ___" will return
[_]
Write a class with a method search that accepts an IP address, and returns the country it's associated with (use the included specific list of mappings in IpToCountry.csv).
The CSV file stores IP addresses as integer values, but the comments at the top tell how to convert to and from them. Let me know if you have any questions.
For example:
"67.99.163.76"will output'United States'
The digital root of a number is the (single digit) value obtained by an iterative process of summing digits, on each iteration using the result from the previous iteration to compute a digit sum. The process continues until a single-digit number is reached.
For example, the digital root of 65,536 is 7, because 6 + 5 + 5 + 3 + 6 = 25 and 2 + 5 = 7.
The digital root of of an array of numbers can be calculated similarly. Using a similar example to the above, the digital root of [ 6, 55, 3, 6 ] is also 7.
Please determine which subsets of [ 1, 2, 3, 4, 5, 6, 7, 8 ] meet ALL of the following properties:
- Contain between 3 and 5 elements.
- Contain the number 5.
- Have a digital root of 9.
