728x90 해설1 [Codility] Lesson4 - Counting Elements : Perm Check (c++) Problem A non-empty array A consisting of N integers is given. A permutation is a sequence containing each element from 1 to N once, and only once. For example, array A such that: A[0] = 4 A[1] = 1 A[2] = 3 A[3] = 2 is a permutation, but array A such that: A[0] = 4 A[1] = 1 A[2] = 3 is not a permutation, because value 2 is missing. The goal is to check whether array A is a permutation. Write a f.. 2020. 12. 20. 이전 1 다음 728x90
