LinkDescriptionYou task was to find minimal natural number N, so that n! contains exactly Q zeroes on the trail in decimal notation. As you know n! = 1*2*...*n. For example, 5! = contains one zero on the trail.InputInput starts with an integer T (≤10000), denoting the number of test cases.Each case contains an integer Q (1≤q≤108) in a line.OutputFor each case, print the case

need a computer program to minimize the cost. You don ' t know some very cheap software gurus?-in fact, I do. You see, there are this programming contest going on ... Help the Prime minister to find the cheapest prime path between any and given Four-digit primes! The first digit must be nonzero, of course. Here's a solution in the case above. 1033 1733 3733 3739 3779 8779 8179 The cost of this solution is 6 pounds. Note that the digit 1 which got pasted over step 2
