![]() You are given a class Solution and an inner class Inner.Private. String s consists of English alphabetic letters and/or decimal digits only.Given a string, s, print its SHA-256 hash value. It undergoes 64 rounds of hashing and calculates a hash code that is a 64-digit hexadecimal number. SHA-256 is a 256-bit ( byte) hashing algorithm which can calculate a hash code for an input of up to 264 – 1 bits. It consists of six identical hashing algorithms (i.e., SHA-256, SHA-512, SHA-224, SHA-384, SHA-512/224, SHA-512/256) with a variable digest size. Secure Hash Algorithm 2 (SHA-2) is a set of cryptographic hash functions designed by the National Security Agency (NSA). In addition, cryptographic hash functions are extremely collision-resistant in other words, it should be extremely difficult to produce the same hash output from two different input values using a cryptographic hash function. By comparing the computed hash (i.e., the output produced by executing a hashing algorithm) to a known and expected hash value, a person can determine the data’s integrity.įor example, computing the hash of a downloaded file and comparing the result to a previously published hash result can show whether the download has been modified or tampered with. The second integer denotes the number to be checked.Ĭryptographic hash functions are mathematical operations run on digital data. The first integer specifies the condition to check for (1 for Odd/Even,2 for Prime, or 3 for Palindrome). The T subsequent lines each describe a test case in the form of 2 space-separated integers: The first line contains an integer, T (the number of test cases). The locked stub code in your editor will print T lines of output. Input is handled for you by the locked stub code in your editor. PerformOperation isPalindrome(): The lambda expression must return true if a number is a palindrome or false if it is not.PerformOperation isPrime(): The lambda expression must return true if a number is prime or false if it is composite.PerformOperation isOdd(): The lambda expression must return true if a number is odd or false if it is even.Write the following methods that return a lambda expression performing a specified action: ![]() The total number of characters in all test cases will not exceed 10 6. The N subsequent lines each contain a line of text.Įach line contains a maximum of 10 4 printable characters. The first line of input contains a single integer, N (the number of lines). ![]() Tags can consist of any printable characters. For example, in contentsinvalid, contents is valid but invalid is not valid.
