Got presentation error in public test case and TLE in private any chance of round 2 for me? :pleading_face:

Yes what i did is -

def ispali(s):
    r = s[::-1]
    return (r==s)

cnt=0

st , en = map(int,input().split(' '))
for i in range(st,en+1):
    s1 = str(i)
    for hr in range(0,24):
      s2 = (2-len(str(hr)))*'0' + str(hr)
      for mini in range(0,60):
          s3 = (2-len(str(mini)))*'0' + str(mini)
          for sec in range(0,60):
              s4 = (2-len(str(sec)))*'0' + str(sec)
              if(ispali(s1+s2+s3+s4)):
                  cnt+=1

print(cnt)

#approach 2

cnt=0
for i in range(st,en+1):
    for j in range(0,86400):
        x = j
        hr = x//3600
        x = x%3600
        mini = x//60
        x = x%60
        sec = x%60
        
        s2 = (2-len(str(hr)))*'0' + str(hr)
        s3 = (2-len(str(mini)))*'0' + str(mini)
        s4 = (2-len(str(sec)))*'0' + str(sec)
        
        if(ispali(str(i) + s2+s3+s4)):
            cnt+=1
print(cnt)

Do they give partial marking for not passing all the test cases??

35

Many people has share ss of graph in tcscodevita contest,
from where they get the graph and after what time ending of zone 1
