Answer-21: It extracts elements that match a pattern.
Question-22. How do you solve an equation?
Answer-22: Using Solve, e.g., Solve[x^2 == 4, x].
Question-23. How do you solve a differential equation?
Answer-23: Using DSolve, e.g., DSolve[y'[x] == y[x], y[x], x].

Answer-26: Using Integrate, e.g., Integrate[x^2, {x, 0, 1}].
Question-27. How do you create a recursive function?
Answer-27: Using f[n_] := f[n - 1] + f[n - 2].
Question-28. What is Nest used for?
Answer-28: It applies a function repeatedly, e.g., Nest[f, x, 3].
Question-29. How do you define a pure function?
Answer-29: Using Function, e.g., Function[x, x^2] or #^2 &.
Question-30. What is MapThread used for?
Answer-30: It applies a function across multiple lists.
Question-31. How do you create an association (key-value pairs)?
Answer-31: Using `<
Question-32. How do you retrieve a value from an association?
Answer-32: Using assoc["key"].
