Question: Juan Marquinho is a geologist and he needs to count rock samples in order to send to a chemical laboratory. He has a problem: The laboratory only accepts rock samples by a rar of its size in ppm (parts per million). Juan Marquinho receives the rock samples one by one and he classifies the rock samples according to the range of the laboratory. This process is very hard because the number of rock

Question: Juan Marquinho is a geologist and he needs to count rock samples in order to send it to a chemical laboratory. He has a problem: The laboratory only accepts rock samples by a range of its size in ppm (parts per million). Juan Marquinho receives the rock samples one by one and he classifies the rock samples according to the range of the laboratory. This process is very hard because the number of rock samples may be in millions. Juan Marquinho needs your help, your task is to develop a program to get the number of rocks in each of the ranges accepted by the laboratory. Input Format An positive integer S (the number of rock samples) separated by a blank space, and a positive integer R (the number of ranges of the laboratory); A list of the sizes of S samples (in ppm), as positive integers separated by space R lines where the ith line containing two positive integers, space separated, indicating the minimum size and maximum size respectively of the ith range. Output Format R lines where the ith line contains a single non-negative integer indicating the number of the samples which lie in the ith range. Constraints . 10<S< 10000 . 1<R< 1000000 • 1 size of each sample (in ppm) < 1000 Example 1 Input: 10 2 345 604 321 433 704 470 808 718 517 811 300 350 400 700 Output: 24 Explanation: There are 10 samples (S) and 2 ranges (R). The samples are 345 604 321 433 704 470 808 718 517 811. The ranges are 300-350 and 400-700. There are 2 samples in the first range (345 and 321) and 4 samples in the second range (604, 433, 470, 517). Hence the two lines of the output are 2 and 4
