Math instruction: Math instructions refer to all output instructions that uses the data of two words or registers and perform the desired function. Math instructions are programmed based on the type of processor used. The data manipulation instructions are almost similar to math instructions. Math instructions are normally used to perform arithmetic functions on the values stored in memory words or registers. Math functions: The basic math functions performed by PLCs are as follows: Addition This function is used to add one piece of data to another. It is also called as ADD. Subtraction This function is used to subtract one piece of data from another. It is also called as SUB. Multiplication This function is used to multiply one piece of data by another. It is also called as MUL. Division This function is used to divide one piece of data from another. It is also called as DIV. MOV instruction: Move (MOV) instruction is used to copy the data of the source register into destination register. Here, the contents of the source register will not be altered. In other words, it is used to copy the value in one word or register to another word or register. Terms used: The following terms are used in the instruction. Source A Source A refers to the address of the first piece of data that is used in the instruction. Source B: Source B refers to the address of the second piece of data that is used in the instruction. Destination Destination refers to the address where the results of the instruction are stored.

Program Plan Intro

Math instruction:

Math instructions refer to all output instructions that uses the data of two words or registers and perform the desired function.

Math instructions are programmed based on the type of processor used.

The data manipulation instructions are almost similar to math instructions.

Math instructions are normally used to perform arithmetic functions on the values stored in memory words or registers.

Math functions:

The basic math functions performed by PLCs are as follows:

Addition

This function is used to add one piece of data to another.

It is also called as ADD.

Subtraction

This function is used to subtract one piece of data from another.

It is also called as SUB.

Multiplication

This function is used to multiply one piece of data by another.

It is also called as MUL.

Division

This function is used to divide one piece of data from another.

It is also called as DIV.

MOV instruction:

Move (MOV) instruction is used to copy the data of the source register into destination register.

Here, the contents of the source register will not be altered.

In other words, it is used to copy the value in one word or register to another word or register.

Terms used:

The following terms are used in the instruction.

Source A

Source A refers to the address of the first piece of data that is used in the instruction.

Source B:

Source B refers to the address of the second piece of data that is used in the instruction.

Destination

Destination refers to the address where the results of the instruction are stored.

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)

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)
