I write the code in idle python 2.7.5 and when I write the same code here and selected python 2.7.13 it shows me NZEC runtime error. please help me someone.
It will avoid a WA but NZEC errors are caused due to some other bugs. Generally, the modifications in output will fall under WA as when the output(correct) and output(generated) will not match. But NZEC error is a type of runtime error, which is caused when the online compiler encounters a sudden anomaly while running the code.
