yeah acc to options it shud be 64 !! going by last 2-digits will be very lengthy

see 36! have 8 zeros and 24! will have 4

so wen we subtract fr last 2 non zerodigit we’ll have
xxx00- last 2 non zero digit of 24!

now last non zerodigit of 24! is 6
so ans has to be in form of x4 using options 64!! (but yeah risky!! as none of dese is dere) u cn find last two digits also bt a bit lengthy
