SQL query:

To create a table in SQL, the programmer must know about syntax for the code.

The syntax for creating a table is as follows:

CREATE TABLE TABLE_NAME (

Column1 datatype,

Column2 datatype,

…

);

The following table “Employee” is created using the below given syntax in SQL.

CREATE TABLE Employee (EMP_NUM CHAR(3) PRIMARY KEY, EMP_LNAME VARCHAR(15), EMP_FNAME VARCHAR(15), EMP_INITIAL CHAR(1), EMP_HIREDATE DATE, JOB_CODE CHAR(3), FOREIGN KEY (JOB_CODE) REFERENCES JOB);

Explanation:

The table named “Employee” was created using the above query as per the given data types. The data type for “EMP_NUM”, “EMP_INITIAL”, and “JOB_CODE” is given as “CHAR”. The data type for “EMP_LNAME”, “EMP_FNAME” is “VARCHAR” and the data type for “EMP_HIREDATE” is given as “DATE”.

Design a dynamic programming algorithm for the Longest Alternating Subsequence problem described below: Input: A sequence of n integers Output: The length of the longest subsequence where the numbers alternate between being larger and smaller than their predecessor The algorithm must take O(n²) time. You must also write and explain the recurrence. Example 1: Input: [3, 5, 4, 1, 3, 6, 5, 7, 3, 4] Output: 8 ([3, 5, 4, 6, 5, 7, 3, 4]) Example 2: Input: [4,7,2,5,8, 3, 8, 0, 4, 7, 8] Output: 8 ([4, 7, 2, 5, 3, 8, 0,4]) (Take your time with this for the subproblem for this one)

Design a dynamic programming algorithm for the Coin-change problem described below: Input: An amount of money C and a set of n possible coin values with an unlimited supply of each kind of coin. Output: The smallest number of coins that add up to C exactly, or output that no such set exists. The algorithm must take O(n C) time. You must also write and explain the recurrence. Example 1: Input: C24, Coin values = = [1, 5, 10, 25, 50] Output: 6 (since 24 = 10+ 10+1+1 +1 + 1) Example 2: Input: C = 86, Coin values = [1, 5, 6, 23, 35, 46, 50] Output: 2 (since 86 = 46+35+5)

Design a dynamic programming algorithm for the Longest Common Subsequence problem de- scribed below Input: Two strings x = x1x2 xm and y = Y1Y2... Yn Output: The length of the longest subsequence that is common to both x and y. . The algorithm must take O(m n) time. You must also write and explain the recurrence. (I want the largest k such that there are 1 ≤ i₁ < ... < ik ≤ m and 1 ≤ j₁ < ... < jk ≤ n such that Xi₁ Xi2 Xik = Yj1Yj2 ··· Yjk) Example 1: Input: x = 'abcdefghijklmnopqrst' and y = 'ygrhnodsh ftw' Output: 6 ('ghnost' is the longest common subsequence to both strings) Example 2: Input: x = 'ahshku' and y = ‘asu' Output: 3 ('asu' is the longest common subsequence to both strings)
