Available question text
Given four numbers 1–9, determine whether you can permute them and insert binary operators (+, −, *, /) and parentheses to form an expression that evaluates to 24 (division is real; no concatenation or unary minus). This is a combinatorial search/backtracking problem over permutations and binary operation orders, requiring careful handling of floating-point comparisons.
