For example finding fib(5):
Work through it from the top down as per the tree diagram below. When the function returns a value at the bottom, work your way back up replacing each function call with the value it returns and you will reach the answer which is 5.

                                  fib(5-1)                     +                      fib(5-2)
                  fib(4-1)           +          fib(4-2)                 fib(3-1)        +        fib(3-2)
      fib(3-1)       +     fib(3-2)       fib(2-1) + fib(2-2)       fib(2-1) + fib(2-2)               1
fib(2-1) + fib(2-2)            1              1     +    0              1     +     0               
    1    +    0  

I don't understand how it should work...

on fingers

how did you calculate it?)

thx) i'll remember this.

if the number is 100, then in this way the calculation will be 50,000 years

I am sorry to hear about your whole head.

Your code is broken because it tries to get a token that is not there.

The fault lies in this code when names >= 4

while (st.hasMoreTokens()) {
    str1 += st.nextToken() + " ";
    str2 += st.nextToken() + " ";
}

You can see that if there is an ODD number of names (>= 4) then that last str2 assignment will fail when it runs out of tokens. E.g. if there are 5 names then:

• loop #1 will read token1 and token2, then
• loop #2 will read token3 and token4, then
• loop #3 will read token5 .... and then crash because token6 does not exist.

e.g. try this:

assertEquals("Alex, Jacob and 3 others like this", Solution.whoLikesIt("Alex", "Jacob", "Mark", "Max", "Bob"));

Yes, it's useless.
