/*************************************************Debugging Tips****************************************************/

// If aplying ceil, floor, pow, etc convert it llo lleger
// Whenever using stacks,queues,etc always check that their top / front / back elements are not accessed when they are empty, thus causing runtime error
// Always consider the possibility of binary search
// Think twice before using greedy
// Always check that any index is not going to be negative
// Remember losing 1 or 2 minutes is better than a penalty of 10 minutes
// Use log2 instead of log()/log(2) to avoid shitty errors
// If declaring a large array, define it globally
// Always initialise anything while declaring, which will not be taken as input
// In case of a problem having decimal calculations, try declaring everything in double rather than typecasting in each step
// Always declare the array with n+5 elements to avoid unexpected errors
// Every problem cannot be solved by DFS easily, think of BFS too
// Never use accumulate
// Use __builtin_popcountll(mask) for counting number of set bits in mask to avoid TLE
// In some problems it has some constant solution for large n and a polynomial solution for small n so that it can be easily solved, keep that in mind
// Use upper_bound(all(v),x,greater<ll>()) for reverse of upper_bound, i.e finding greatest element less than x, v should be reverse sorted
// Use s.lower_bound(x) in set and multiset, the other one has linear complexity
// pow(a,b) does not provide exact results sometimes, use a loop instead
