print(len("hello"))            // -> 5

// to_number with various string inputs

print(to_number("   -7  "))    // -> -7
print(to_number("12a"))        // non-numeric suffix -> 0
print(to_number(""))           // empty -> 0
print(to_number("  "))         // spaces -> 0

// to_string on numbers and arrays
print(to_string(42))           // -> "42" (printed as 42)
