Count Buses Exceeding Distance Threshold

You are given a list of buses with their traveled distances. Your task is to count the number of buses that have traveled more than a given threshold distance k kilometers. The first line of the input contains two integers: n (the number of buses) and k (the threshold distance). This is followed by n lines, each containing two integers: bus_id and distance.

In mathematical terms, you need to compute the value of:

[ \text{count} = \sum_{i=1}^{n} [d_i > k], ]

where \(d_i\) is the distance traveled by the \(i\)-th bus, and the indicator function \([d_i > k]\) equals 1 if \(d_i > k\) and 0 otherwise.

Output the computed count.

inputFormat

The input is read from stdin and has the following format:

• The first line contains two integers n and k, separated by a space.
• The next n lines each contain two integers: bus_id and distance.

outputFormat

The output is written to stdout and should be a single integer representing the number of buses whose traveled distance is strictly greater than k.
