# circuits – Does the number of occurrences count in NC¹?

Leave $$c ℕ₊ ℕ₊$$ be constant and $$p∈ {0,1 } ^ c$$ a fixed bit pattern wide $$c$$.

Suppose the input length is structured as a block list $$b_1 … b_n$$, each block has width $$c$$; Is it possible to calculate the number of blocks the same? $$p$$ (that is to say., $$bigl lvert {i ) in binary with a family of NC¹ circuits with uniform record space? Why or why not?
