In this lab, you will determine the least common multiple (LCM) of two numbers in memory named datax and datay. The calculated LCM value should be stored in the area of memory directly following the given data. To calculate the LCM, you can first find the greatest common divisor (GCD) of the two numbers and use the formula LCM(x,y)*GCD(x,y) = x*y. To find the GCD, you can use Dijkstra's Algorithm to forgo the use of division or modulus functions. Pseudocode (C code) for Dijkstra's Algorithm used to find the GCD is as follows: int GCD(int x, int y) { if(x == y) return x; else if(x > y) return gcd(x-y, y); else return gcd(x, y-x); } Notice that you are passing values in and out of subroutines, which is the focus of lecture this week. You may choose any of the 3 methods (pass by registers, reference, or stack) that you feel is most appropriate.

In this lab, you will determine the least common multiple (LCM) of two
numbers in memory named datax and datay. The calculated LCM value
should be stored in the area of memory directly following the given data. To
calculate the LCM, you can first find the greatest common divisor (GCD) of
the two numbers and use the formula LCM(xy)*GCD(x,y) = x*y.
To find the GCD, you can use Dijkstra's Algorithm to forgo the use of division
or modulus functions. Pseudocode (C code) for Dijkstra's Algorithm used to
find the GCD is as follows:
int GCD(int x, int y) {
if(x == y)
return x;
else
if(x > y)
return gcd(x-y, y);
else
return gcd(x, y-x);
}
Notice that you are passing values in and out of subroutines, which is the
focus of lecture this week. You may choose any of the 3 methods (pass by
registers, reference, or stack) that you feel is most appropriate.

In C programming Language: use the correct program and function descriptions. use a user defined function for the sequential search and it must use pointers to keep track of the number of successful searches as well as how many test comparisons were made. use the srand() function and offset and range correctly. create and use arrays. to search an array using a sequential search. to use sound programming practices. use of a function and pointers. You are tasked to create a program that will create an array of 100 random integers in the range of 1 to 200 (inclusive) once. Array may contain duplicate values. Your program will then randomly generate a search target/value in the same range of 1 to 200 and perform a sequential search on the array of stored random values 100 times. Your program should print out the following statistics: The number of successful searches ( a match was found). The number of failed searches. (no match was found in the array) The average number of tests…

you will write a c++ program to input 5 elements (of type int) from the user and store them in an array. Your program should then reverse the array and display it. For instance, if the user enters 1 2 3 4 5 as the five elements of the array, your program should reverse it and display: 5 4 3 2 1 Note: You must use a for loop to process the array.
Assignment for Computer Architecture You are to write a program in MIPS that computes N! using a loop. Remember N! is the product of all the numbers from 1 to N inclusive, that is 1 x 2 x 3 x (N – 1) x N. It is defined as 1 for N = 0 and is undefined for values less than 0. The program first requests the user to input the value of N (display a prompt first so the user knows what to do). If the input value is less than 0, the program is to display “N! undefined for values less than 0” and request input again. If the value input is non-negative, it is to compute N! using a loop. You are to have your name, the assignment number, and a brief description of the program in comments at the top of your program. Since this is an assembly language program, I expect to see comments on almost every line of code in the program. Also make the code neat (line up the commands and comments in nice columns)
Write a function that returns the greatest common divisor of 2 integers.
Complete the tables that follow to describe the memory addresses and values of each variable when the last statement in the ChangePasscode function is performed (right before the function exits). Note: Operating systems may use different rules for assigning memory addresses. For this worksheet let us assume that the compiler will use up the greater memory address first (e.g., if 0x7ffd151a1d58 and 0x7ffd151a1d5c are available, it will initialize variables in 0x7ffd151a1d5c first).
This is for r Regarding a for loop, which of the following is not true? The for keyword must be followed by parentheses. Following the for statement, the code to be executed is recognized by it being indented. The number of times the loop will be performed is determined by the length of the vector passed to the for keyword. The for loop can contain other for loops.
