How to remove subarray from array(know the solution for finding subarray)
So guys i have problem here with an idea. So i have written code for determining if some array is subarray in other array. But now I stuck with idea how to remove all these subarrays from array.
My idea is something like this:
To put 2 pointers. One will show on first element of array, and another will show n elements after first element of array(n is the number of elements of subarray). This will only happen if the p1,p1+n(p1 is pointer) is really subarray. (if its not i will write p1++ so i check other 3 elements(i mean if i checked 1. 2. and 3. now i will check 2. 3. and 4.))
I thnik this idea is good, but i stuck somewhere(because i create a lot of copies of pointer p1 because there will be a lot of movemement)
