Coin Flipping Puzzle: Interview Question

Golu has 100 identical coins (with head side and tail side) which he wants to donate to someone. There are many people who are aiming to get this collection of 100 coins. So Golu created a puzzle using all 100 coins and declared that the one who will solve his puzzle will get all the coins. You desperately need money so solving the puzzle is only option you have. The Problem goes like this: All 100 coins are laying flat on a table. 80 of them are heads up and remaining 20 are tails up. You can’t feel, see or in any other way find out which side is up. Split the coins into two piles(sets) such that there are the same number of tails in each pile. [Baby Hint]: If number of coins in first pile is n then other pile will have 100-n coins. First try yourself before peeking into the solution below.

JSON vs YAML

JSON JSON(JavaScript Object Notation) is a human-readable data exchange format. JSON is built on two structures: A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. JSON's basic data types are: Number : a signed decimal number that may contain a fractional part and may use exponential E notation, but cannot include non-numbers such as NaN. The format makes no distinction between integer and floating-point. JavaScript uses a double-precision floating-point format for all its numeric values, but other languages implementing JSON may encode numbers differently. String : a sequence of zero or more Unicode characters. Strings are delimited with double-quotation marks and support a backslash escaping syntax. Boolean : either of the values true or false Arra

[Fixed] Alexa can count only from 1 to 10

Note : At the time of writing this post, Alexa had this issue which has been resolved. Alexa can now count flawlessley even in reverse. Alexa is the smart virtual assistance by Amazon. It is beating google now and Siri on non-screen devices. Alexa is hailed for its intelligence but it seems that the Alexa knows to count only from 1 to 10. By 1 to 10, I mean exactly from 1 to 10; neither more nor less. Even asking Alexa to count from 1 to 5 or 3 to 10 or 3 to 5 results in an apology from Alexa. Watch the above video to see for yourself.
