Athlete Race Time Tracker

The city is organizing an annual sports event where multiple athletes compete in various races. Each athlete is identified by a unique number, and in each race, the athlete records a time in seconds. You are given a sequence of queries to update and retrieve athletes' times.

There are two types of queries:

• Type 1: "1 a r t" — Add an entry for athlete a with time t (in seconds) for race r. The race identifier r is provided but does not affect the query outcome.
• Type 2: "2 a" — Output the total accumulated time of athlete a across all races. Formally, if athlete a has recorded times \(t_1, t_2, \dots, t_k\), then the total time \(T_a\) is given by: $$T_a = \sum_{i=1}^{k} t_i.$$

If an athlete has no recorded times when queried, output 0.

inputFormat

The first line contains an integer n which indicates the number of queries.

Each of the following n lines contains a query. A query is in one of the following formats:

• Type 1: 1 a r t — where a and t are integers representing the athlete's identifier and time (in seconds), and r is the race identifier (unused in the calculation).
• Type 2: 2 a — where a is an integer representing the athlete whose total time is to be output.

outputFormat

For each query of type 2, output a single line with the total time (in seconds) accumulated by the athlete. The output should be printed in the order the queries appear.
