node in a loop and then output the node. The data is too weak. For example, if the fruit tree is a long chain, gcd = 1 at the bottom and other nodes, and the last node is queried every time, the time-out will occur.I tried it just now. It seems that none of Solution can avoid TLE. It's all about violence. Wait for the official solution. Below is the data generator of the TLE data written in pyt

Because this topic explains the precedence rules, it is possible to operate directly from left to right, and in the case of nested parentheses, you can use a recursive method, given the right and left bounds of each parenthesis, with the pseudo-code as follows:int Cal () {if (parentheses) sum + = Cal ();else sum + = num;return sum;}But this topic really pits me a bit, saw WA, have not seen tle ...
