comment conversion from string to json object android
@Phil That doesn't appear to be a valid java String assignment. I don't understand what I am doing differently though JSONObject obj = new JSONObject("Fat cat":"meow"); I figured it out, I needed to use \ infront of the quotes, and then actual quotes around the whole thing. Thanks.

comment conversion from string to json object android
@Phil This does not appear to work if I change json to "Fat cat" or any other simple string like that. What is going on? I just pass to the catch block.

comment Recurrence Relation: Solving Big O of T(n-1)
@AndreasJansson I do not follow your algebra on the first two steps. You claim that $T(n-1) + 2 = (T(n-2) + 2) + 2$ but I do not see how you come to this conclusion. Nothing in the problem hints at this so how can you make this assumption? What if $T(2) = 10000000000000000$ we don't know so how can you assume that it isn't?

Yes I see that but how did you figure out to extract the numbers in that manner?

Where id 64 come from?

so if we are working with mod 3 then 1, 4, 7, 11 and so on are all replaceable regardless of their power?

Why are you using negative numbers in modulo arithmetic? Why does it matter if a number if negative?

comment Finding the mod of a difference of large powers
I know a little bit of modular arithmetic and the idea of congruence, I am just not familiar with the math heavy notation and acronyms.

I don't know the binomial theorem either but how is it that you are taking the powers of 4 and 9 and turning them both into 1?

I don't understand the $6 | 1536$ part, what does that mean?

I don't follow that logic, can you demonstrate with a more simple example?

Can you explain your notation, I am not familiar with it enough to read this commit. I don't know what the : implies, I don't know what CRT is, I don't know what lcm is either. Thanks.

It was there but I meant that I tried to use it and was unable.

Yes I see that but you are making the claim that some number (that is not 1) is equal to 1. I do not see how that stands.
