Recently, we found that the toFixed () method in JS has some problems. When we use the toFixed () method on the prototype object of the native Number object, the rule is not a so-called "Rounding" or "four homes, six homes, five homes, and five into double". The so-called "four homes, six

build a tree of weights segment (for all L, R, A discretization will save time and space), from each J corresponding to the a[j] node to the J-connected INF Edge, from the line tree node to the node's son node to the edge of the INF, for each I, then the line tree to find the corresponding [L[i], R[i] ] interval, from n + I to the nodes that make up these intervals are connected to the INF edge.However, we have not considered the J One thing to note is that for the I position, insert a[i], is b
