Given an integer array data representing the data, return whether it is a valid UTF-8 encoding (i.e. it translates to a sequence of valid UTF-8 encoded characters). • A character in UTF8 can be from 1 to 4 bytes long, subjected to the following rules: • For a 1-byte character, the first bit is a 0, followed by its Unicode code. • For an n-bytes character, the first n bits are all one's, the n + 1 bit is 0, followed by n - 1 bytes with the most significant 2 bits being 10. • This is how the UTF-8 encoding would work: • Number of Bytes | UTF-8 Octet Sequence • | (binary) • -------------------+---------------------------------------- • 1 | 0xxxxxxx • 2 | 110xxxxx 10xxxxxx • 3 | 1110xxxx 10xxxxxx 10xxxxxx • 4 | 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx • x denotes a bit in the binary form of a byte that may be either 0 or 1. • Note: The input is an array of integers. Only the least significant 8 bits of each integer is used to store the data. This means each integer represents only 1 byte of data. • • Example 1: • Input: data = [197,130,1] • Output: true • Explanation: data represents the octet sequence: 11000101 10000010 00000001. • It is a valid utf-8 encoding for a 2-bytes character followed by a 1-byte character. • Example 2: • Input: data = [235,140,4] • Output: false • Explanation: data represented the octet sequence: 11101011 10001100 00000100. • The first 3 bits are all one's and the 4th bit is 0 means it is a 3-bytes character. • The next byte is a continuation byte which starts with 10 and that's correct. • But the second continuation byte does not start with 10, so it is invalid. • • code https://github.com/anandchauhan21/dai... • profile https://linktr.ee/anandchauhan
