Brute Force Algorithms

A club with 10 students elects a president, vice president, treasurer, and secretary. No student can hold more than one position. How many ways are there to select the class officers?

Brute Force Algorithms

How many ways are there to arrange the letters in the word ALGORITHMS? Note, the letter arrangement does not have to spell a word in the dictionary, but the new word must contain all the letters and each letter can be used only once.

Hint: Start with shorter words (e.g ALG or ALGO) and see if a pattern emerges with the number of possible arrangements.

Create a flowchart that display even numbers from n (entered by the user) to 2.

Solve following scenarios (draw truth tables, write equation and design logic gate diagram): 

CLO#3 

Scenario1

Detecting the standing bottles on the conveyor and pushing falling bottles in tray.

Number of Inputs Required

X0 – Proximity Sensor to sense bottom of the Bottle i.e. X0 = ON when the     detected input signal from the bottle-bottom is sheltered.

X1 – Proximity Sensor to sense upper part of the Bottle i.e. X1 = ON when the detected input signal from the bottle-neck is sheltered.  

Number of Outputs Required

Y0 – To operate Pushing Cylinder/Rod

Scenario2

Switching on/off the Lamp whether they are at the bottom or the top of the staircase

Number of Inputs Required

X0 – Switch at the bottom of Staircase i.e. X0 turns ON when the bottom switch is turned to the right.

X1 – Switch at the top of Staircase i.e. X1 turns ON when the top switch is turned to the right.

Number of Outputs Required

Y0 – Lamp
