String theory tries to model the four known fundamental interactionsgravitation, electromagnetism, strong nuclear force, weak nuclear forcetogether in one theory. in the 1 . Expand the exponential, then sum over contractions between T and the sum (there will be zero, one, or two contractions), and then do the sum, which should simplify if you've done the combinatorics . Rather self-descriptive - a short explanation of string theory.DISCLAIMER!String Theory is not a settled issue. Other than .toUpperCase and .toLowerCase, don't use any string methods.Sure, .slice would be nice here, but you'll learn just a ton more if you use actual loops! -1 refers to the last character, -2 refers to the second last character, and so on.
