Lets solve some real problems

Project euler: 1

• problem
• inputs:
  • max: 10
• solution

result = 0 (Remember 0 as result)
max = 10
index = 1
until index < max
    if index % 3 == 0 or index % 5 == 0  then
        result = result + index
    endif
    index = index + 1
say result

Project euler 2

• problem
• Let me create a fibbonaci sequence

sum = 2
a = 1
b = 2

until a + b < 100
    c = a + b
    if c%2 == 0 then
       sum = sum + c
    endif
    a = b
    b = c
say sum

• Prompt:

To solve Fibonacci sequence is generated by adding the previous two terms.By considering the terms in the Fibonacci sequence whose values do not exceed 50 

i have written the following psuedo code (my own language ), help in executing this  

sum = 2
a = 1
b = 2

until a + b < 50
    c = a + b
    if c%2 == 0 then
       sum = sum + c
    endif
    a = b
    b = c
say sum

Solve this

• Find if the number is prime or not
• Find factors of 100
