PROGRAM TO CALCULATE SQUARE ROOT OF A NUMBER

Algorithm:

read(n);
Step1:Take a initial guess guess1=some arbitary value (close to the number);
Step 2:Divide the number n by initial guess and store it in a variable g =n/guess1;
Step 3: Take the average of guess1 and g and store if guess2 ,guess2 = (guess1+g)/2;

repeat the process untill guess2 is less than guess1

while(guess2 {
guess1=guess2;
g=n/guess1;
guess2=(guess1+g)/2;
}

print(guess2);
