Problem 1:

(RULES
f(0(x1:S)) -> 0(x1:S)
f(s(x1:S)) -> s(s(f(p(s(x1:S)))))

Problem 1: 

Innermost Equivalent Processor:
-> Rules:
 f(0(x1:S)) -> 0(x1:S)
 f(s(x1:S)) -> s(s(f(p(s(x1:S)))))
 p(s(x1:S)) -> x1:S
-> The term rewriting system is non-overlaping or locally confluent overlay system. Therefore, innermost termination implies termination.
