// use (a+b-1)/b instead of ceil(a*1.0/b), as it does not suffer from floating point imprecision

// BEFORE SUBMISSION, 
// 1. check for uninitialised variables, 
// 2. check for possible int overflow, 
// 3. check for precision issues, 
// 4. check for invalid index access 

// Don't get stuck on one approach, incorrect approach causes more WA than incorrect implementation.
