!! 测试input和arr语法

!! 测试arr数组语法
show(`=== Testing arr() ===`);
arr1 = arr(`apple`, `banana`, `cherry`);
show(`Created array: `, arr1);
show(`Array length: `, len(arr1));

!! 测试数组操作
arr1 = push(arr1, `date`);
show(`After push('date'): `, arr1);

arr1 = pop(arr1);
show(`After pop(): `, arr1);

show(`indexOf('banana'): `, indexOf(arr1, `banana`));

!! 测试input语法（带提示）
show(`\n=== Testing input() ===`);
show(`Please enter your name:`);
name = input(`Name: `);
show(`Hello, `, name, `!`);
