Create pushdown automata for the following languages. Start each one by briefly outlining your plan in English, explaining how the stack will be used. Also give five good strings in the language. Then give a PDA diagram and formal definition for all parts.

L1 = { (x U y U z)*, number of xs > number of zs, = {x, y, z} }

L2 = { aⁿb^n+ma^m, n, m >= 0, = {a, b} }

L3 = { 1ⁿ2ⁿ3^m4^m, = {1, 2, 3, 4} }

L4 = { xw | x^R is a prefix of w,

x & w are elements of (a U b)⁺,

|w| > |x| }
