Not a kata issue. You're trying to create arrays that are too big, try solving it another way.

Getting this error (FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory) but passing all tests.

That did fix it, but code now pretty ugly due rust's strict type checks. Thanks.

@MrZizoScream: how is it that you're 5kyu now? O_o

• Thanks for posting your question but for more help you could make use of Question Lable
• I'm not a rust Coder But I'll try to help as I can ,

Is the checker picking up the '-' in fn tadd(x: u32, y: u32) -> u32 as a minus sign?

• Big Yes, The Checker doesn't differentiate between minus sign of function and mathematical operations, it just scans for Char '-' , Thus the failure message had appeared, but you can take a step to prevent it which is including your foo's function body into the main function, I mean cutting your solution and pasting it into the main function add Without changing, This Will be Complied and run as success
• Tuned to hear Your Feedback .. Regards .. Zizou

In rust, I am getting "solution contains a '-'." failure.

Is the checker picking up the '-' in

fn tadd(x: u32, y: u32) -> u32 {

as a minus sign?

Try running it with x = -1740173806, y = 1048100893 and you'll see why.
