i read total number of substrings can formed given string n^2 don't understand how count this. by substrings, mean, given string cat, substrings be: c ca cat @ t the total number of (nonempty) substrings n + c(n,2) . leading n counts number of substrings of length 1 , c(n,2) counts number of substrings of length > 1 , equal number of ways choose 2 indices set of n . standard formula binomial coefficients yields c(n,2) = n*(n-1)/2 . combining these 2 terms , simplifying gives total number (n^2 + n)/2 . @rici in comments notes same c(n+1,2) makes sense if e.g. think in terms of python string slicing substrings of s can written in form s[i:j] 0 <= < j <= n (with j being 1 more final index). n = 3 works out (9 + 3)/2 = 6 . in sense of complexity theory number of substrings is o(n^2) , might read somewhere.
