[HINTS] If You Look for Observations + Hints + Test Cases Come Over!
Observations\n1) Number of 1s should be dived by 3 with no remainder\n2) We can skip the leading zeros in the middle except trailing zeros\n3) Number of Middle 
**Observations**\n1) Number of 1s should be dived by 3 with no remainder\n2) We can skip the leading zeros in the middle except trailing zeros\n3) Number of Middle zeros should be at least as num of trailing zeros\n\n**Some Good Test Cases**\n```\n[1,0,0,1,0,0,1,0,0]\n[1,0,0,1,0,0,0,1,0,0]\n[0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0]\n[0,0,1,1,1]\n[1,0,0,1,1]\n[1,1,0,0,1]\n[1,1,1,0,0]\n[1,1,0,0,1,0,0]\n[1,0,0,1,1,0,0]\n[0,0,1,1,1]\n[1,0,0,1,1]\n[1,1,0,0,1]\n[1,1,1,0,0]\n[1,1,1]\n[1,1,1,1]\n[1,1,1,1,1]\n[1,1,1,1,1,1]\n```
