如何以编程方式将表达式括起来？

expression = "1 + 2 * 3"
bracketed_expression = "(" + expression + ")"
print(bracketed_expression)

const expression = "1 + 2 * 3";
const bracketedExpression = "(" + expression + ")";
console.log(bracketedExpression);

String expression = "1 + 2 * 3";
String bracketedExpression = "(" + expression + ")";
System.out.println(bracketedExpression);

string expression = "1 + 2 * 3";
string bracketedExpression = "(" + expression + ")";
Console.WriteLine(bracketedExpression);
