please help with the code in C language

Write a function to unzip an array of length 2n into two arrays of length n each:/* Unzip\s an array into two (opposite of zip). E.g., c: [1, 2, 3, 4 5 6] unzips into a: [1, 3, 5] b: [2, 4, 6] In this case, n is 3. Returns -1 if the input is malformed and 0 otherwise. int unzip(int * a, int * b, int * c, int n)
