Here are some recurrence relations that come up in the analysis of
Quicksort and or Select. For each recurrence, write one sentence
explaining how it relates to Quicksort or Select and give its asymptotic
growth rate in notation.
T(n) = T(n/10) + T(9n/10) + n
T(n) = T(n-1) + n
T(n) = T(n/5) + T(3n/4) + n
