What does run error signifies in coding blocks ide

out of 8 test cases 7 run correctly but 1 one of them shows run error what does this mean

running test case 1(after downloading test case 1) gives correct answer in custom input but while submitting it shows run error

my answer is totally correct as i have seen after downloading test cases but if i submit it shows wrong answer … whats the reason

Can you please share your code by saving it at the given below link and then sharing the same with me here .

n=int(input()) t=0 s=[] for i in range(n): a=int(input()) s.append(a) for i in range(n-1): if s[i]>s[i+1]: continue else: p=i t=1 break for i in range(p,n-1): if s[i]<s[i+1]: continue else: t=2 break if t==0 or t==1: print(“true”) else: print(“false”)

Two major reasons for getting run error are -

  1. using an undefined variable or function.

  2. using operators on the wrong type of data
