Please help with a solution in C

// goal: flattens (the first N rows of) an array // param N: number of elements to scale // param arr: the array to flatten // param flat: the array to store the flattened version of arr in // assumptions: arr has dimensions N by 3, (arr[N][3]) // flat has length 3*N // // example: inputs: // // N = 4 [[ 1, 2, 3], [ 4, 5, 6], [ 7, 8, 9], [10, 11, 12]] // arr = // // // // flat = // outcomes: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12] // flat // // TODO: Complete the function void flatten(int N, int arr[][3], int flat[]) { } |
