Find Regular

Question

Which one is Regular?

1)$L_{1}=\left \{ a^{x}b^{y}c^{z} | \left ( x=y\vee y=z \right ) \wedge x+y+z\leq 100\right \}$

2)$L_{2}=\left \{ a^{x}b^{y}c^{z} | \left ( x=y\vee y=z \right ) \wedge x+y+z\geq 100\right \}$

Comments

L1 is regular (finite no. of strings)

L2 is NCFL

@aditya

for L2, there is NPDA, which is going to accept this. You can easily construct it. just give it a try.
