/*Count first You have been given a sequence of n integers. Lets say the given sequence is a0, a1, a2, a3 ... an-1. You need to find the number of occurrences of the first value (i.e. a0) in the given sequence. Input Format: First line contains an integer n, denoting the length of the sequence. Next n lines contains one integer each. Output Format: One integer, denoting the result, as mentioned above. Example: Input: 5 10 20 30 40 10 Output: 2 Explanation: First line contains 5, meaning the sequence has 5 integers. First element is 10. In the given sequence, 10 occurs 2 times. So, the output is 2. */ let fs = require ( "fs" ); let data = fs . readFileSync ( 0 , 'utf-8' ); let idx = 0 ; data = data. split ( ' \n ' ); function readLine () { idx ++ ; return data[idx - 1 ]. trim (); } //====================================================================================================== let noOfInputs = parseInt ( readLine ()); // 5 let ...
