Problem: In Takahashi Kingdom, there is a east-west railroad and N cities along it, numbered 1, 2, 3, ..., N from west to east. A company called _AtCoder Express_ possesses M trains, and the train i runs from City L_i to City R_i (it is possible that L_i = R_i). Takahashi the king is interested in the following Q matters:    * The number of the trains that runs **strictly within** the section from City p_i to City q_i, that is, the number of trains j such that p_i \leq L_j and R_j \leq q_i.  Although he is genius, this is too much data to process by himself. Find the answer for each of these Q queries to help him.

Problem: In Takahashi Kingdom, there is a east-west railroad and N cities along it, numbered 1, 2, 3, ..., N from west to east. A company called _AtCoder Express_ possesses M trains, and the train i runs from City L_i to City R_i (it is possible that L_i = R_i). Takahashi the king is interested in the following Q matters:    * The number of the trains that runs **strictly within** the section from City p_i to City q_i, that is, the number of trains j such that p_i \leq L_j and R_j \leq q_i.  Although he is genius, this is too much data to process by himself. Find the answer for each of these Q queries to help him.

Problem: In Takahashi Kingdom, there is a east-west railroad and N cities along it, numbered 1, 2, 3, ..., N from west to east. A company called _AtCoder Express_ possesses M trains, and the train i runs from City L_i to City R_i (it is possible that L_i = R_i). Takahashi the king is interested in the following Q matters:    * The number of the trains that runs **strictly within** the section from City p_i to City q_i, that is, the number of trains j such that p_i \leq L_j and R_j \leq q_i.  Although he is genius, this is too much data to process by himself. Find the answer for each of these Q queries to help him.
