The algorithm as :

Step 1: Read N.

Step 2 : Let ctr = 1.

Step 3: Read Num.

Step 4 : large = Num.

Step 5: Read next Num.

Step 6 : ctr = ctr + 1.

Step 7 : If (Num > large) then large = Num.

Step 8 : If (ctr < = N) then repeat steps 5 and 6.

Step 9: Print large.

Step 10: End.

The algorithm is defined as :

Step 1: Read X, Y, Z.

Step 2 : If X > Y continue step 5.

Step 3: If Y>Z then print “Y is the largest “and continue step 7.

Step 4: Continue step 6.

Step 5: If X>Z then print “X is the largest “and continue step 7.

Step 6: Print “Z is largest”.

Step 7: End.

An algorithm is a step by step instructions required to solve any problem. These instructions are in the user’s language that means they are independent of any programming language.

Step 1: Start.

Step 2 : Read a,b,c.

Step 3: s=(a+b+c)/2.

Step 4 : Area = (s(s-a)(s-b)(s-c))^1/2

Step 5 : Print Area.

Step 6: Stop.

Step 1: Start.

Step 2: Read F.

Step 3: C=(5(F-32))/9.

Step 4: Print C.

Step 5: Stop.

The algorithm as :

Step 1: Read N.

Step 2 : Let ctr = 0, sum = 0.

Step 3: Read Num.

Step 4 : ctr = ctr + 1.

Step 5: Compute the square of the number i.e., = sqr (Num * Num).

Step 6 : sum = sum * sqr.

Step 7: If ctr is less than N then repeat steps 3 to 6. 

Step 8: Print sum.

Step 9: End.

The algorithm as :

Step 1: Start.

Step 2 : Input N.

Step 3 : sume = 0.

Step 4 : sumo = 0.

Step 5 : ctr = 1.

Step 6 : while (ctr < = N).

If (ctr mod 2 = 0)

sume = sume + ctr

else

sumo = sumo + ctr.

Step 7: Print “sum of even number is” sume.

Step 8: Print “sum of odd number is” sumo.

Step 9: End.

The algorithm as :

Step 1: Read two numbers A and B.

Step 2: Compare A and B.

Step 3: If A is greater than B then, print A else print B.

Step 4: Stop.

The algorithm is defined as follows :

Step 1: Start.

Step 2: Read the amount in rupees and conversion rate.

Step 3: Calculate the equivalent amount in dollars using the following formula: amount in dollars = amount in rupees/conversion rate.

Step 4: Write the amount in dollars.

Step 5: Stop.

Some properties of the algorithm are :

1. An algorithm should terminate after the finite number of steps.

2. An algorithm should be simple so that anyone can understand them properly.

3. An algorithm should be universal and lead to a unique solution to the problem.

4. An algorithm should have the capability to handle some unexpected situations which may arise during the solution of a particular problem.

5. An algorithm should be able to solve all problems of a particular type for which it is designed.

Some characteristics of the algorithm are :

1. Each and every instruction should be short and clear.

2. Each instruction should be such that it can be performed in a finite time.

3. One or more instructions should not be repeated infinitely.

4. After performing the instructions the desired result must be obtained.

Step 1: Start.

Step 2: Read A, B.

Step 3: Sum=A+B.

Step 4: Print Sum.

Step 5: Stop.

Step 1: Start.

Step 2 : Read RR, T.

Step 3 : SI=(P*R*T)/100.

Step 4 : Print SI

Step 5 : Stop.
