Hello, Suppose w={1,1,1,0,0,1,0,1,0,0,1,0,0}. How can I count the number of occurrences of a 1 in w immediately followed by a 0 in w? I have tried every incarnation of Count[] I can think of; for example, Count[w,{___,1,0,___}] does not seem to work. In general, how can I count the number of occurrences of a 1 followed by a 0 in a list of 1's and 0's? Thank you! -- Tony _____________________ amendes at math.ucsd.edu
