+/*
+Good morning! Here's your coding interview problem for today.
+
+This problem was asked by Google.
+
+UTF-8 is a character encoding that maps each symbol to one, two, three, or four bytes.
+
+For example, the Euro sign, €, corresponds to the three bytes 11100010 10000010 10101100. The rules for mapping characters are as follows:
+
+For a single-byte character, the first bit must be zero.
+For an n-byte character, the first byte starts with n ones and a zero. The other n - 1 bytes all start with 10.
+Visually, this can be represented as follows.
+
+ Bytes   |           Byte format
+-----------------------------------------------
+   1     | 0xxxxxxx
+   2     | 110xxxxx 10xxxxxx
+   3     | 1110xxxx 10xxxxxx 10xxxxxx
+   4     | 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx
+
+Write a program that takes in an array of integers representing byte values, and returns whether it is a valid UTF-8 encoding.
