+#Program 1: Factorial 
+
+Find factorial of any number given
+Factorial of number is calculated by multiplying n*(n-1)
+Sample Input:4
+Factorial: 4*3*2*1
+Output: 24
+Sample input:6
+Factorial: 6*5*4*3*2*1
+Output:720
+
+Method 1 using For loop
+
+f=1
+n = int(input('Sample input:'))
+for i in range(1,n+1):
+    f=f*i
+print(f)
+
+Method 2 using while loop
+
+f=1
+n = int(input(‘Sample input:’))
+while(n>0):
+    f=f*n
+    n=n-1
+print(f)
+
+#Program 2: Guess a Number
+
+Ask a user to guess a number between 1 to 50. He gets only 5 chance to guess. Give user a feedback if his guess is high or low.  
+
+import random
+
+num=random.randint(1,50)
+print("Guess a Number from 1-50 \n You have only 5 chance\n")
+chances=0
+while chances<5:    #you only get 5 chances to guess
+    guess=int(input('Take a guess:'))
+    if guess<num:
+        print('Your guess is too low')
+        chances+=1
+    if guess>num:
+        print('Your guess is too high')
+        chances+=1
+    if guess==num:
+        chances+=1
+        break
+else:
+    print("You ran out of chances")
+if guess==num:
+    print('Nicely Done! You guessed the number in ',chances,' guesses')
+
+#Program 3: FizzBuzz
+
+Consider ‘n’ numbers, print all the numbers from 1 to n and replace some number according to this criteria:
+    • If the number is divisible by 3, write Fizz instead of the number
+    • If the number is divisible by 5, write Buzz instead of the number
+    • If the number is divisible by 3 and 5 both, write FizzBuzz instead of the number
+[Constraints n should be more than 1 and less than 100; i.e., 1<=n<100]
+
+while True:
+    n = int(input("Enter a number(1-100):"))
+    if n>=1 and n<=100:
+        for i in range(1,n+1):
+            if i%3 == 0 and i%5==0:
+                print("FizzBuzz")
+            elif i%3==0:
+                print("Fizz")
+            elif i%5==0:
+                print("Buzz")
+            else:
+                print(i)
+        break
+    else:
+        continue
+
+#Program 4: Neon Number
+
+Enter a number and check whether the number is neon number or not
+Sample input: 9
+Sample output: Yes it is a neon number
+Sample input: 6
+Sample output: No it is not a neon number
+
+***[Neon number explanation: input=9
+Step one: 9*9 =81 
+Step two: 81 = 8+1 = 9
+Step three: 9 == sample input
+Yes it is a neon number]***
+
+n = int(input("Sample input:"))

+sum=0
+while(first_step>0):
+    second_step=first_step%10
