Test case 3 is failed and i am not getting the problem where is : This is my code:

import re

def check(s): #1check if no of digits are 16 or not after removing - if len(s.replace("-",""))==16: for i in s: if i=="-" or i.isdigit(): continue else: return "Invalid"

    pattern=r"[456]\d{3}(-?\d{4}){3}"
    s_new=s.replace('-',"")
    c=1

    #checking repetetion of same digit equal to or more than 4
    for i in range(len(s_new)-1):
        if "-" in s_new:
            match=re.finditer(r"-",s_new)
            index=[x.start() for x in match]
            if index==[3,7,11]:
                pass
            else:
                return "Invalid"

        if s_new[i]==s_new[i+1]:
            c+=1
            if c==4:
                return "Invalid"
            continue
        else:
            c=1
    if c==1:
        if re.match(pattern,s):
            return "Valid"
        else:
            return "Invalid"

else:
    return "Invalid"

n=int(input()) for _ in range(n): s=input() result=check(s) print(result)
