Utf - 8 Encoding
1. You are given an array of integers. 2. You are required to test whether the array represents a valid sequence of UTF-8 characters or not. 3. A character in UTF-8 can be from 1 to 4 bytes long and follows some rules - (i) For 1-byte long character, first bit will be 0 and rest represents its unicode code. (ii) For n-bytes long character, first n-bits will be 1's, the n+1th bit is 0, followed by n-1 bytes with most significant 2 bits being 10. Note -> Only the least significant 8 bits of each element in array is used for data. Note -> Check out the question video for details.
