Well the thing your doing is not optimal. You are checking if first element is bigger than second if yes then you are using the operation but the optimal thing to do is to just apply the operation whenever it gives a lesser number than the current number and also maintains that the previous value is smaller

k-a[i] can be larger than or equal to a[i-1] (k >= a[i] + a[i-1])

Instead, you should check for k-a[i] instead of k-a[i-1], if k-a[i] and doesn't work then just straight up cout << "NO"

Fun fact about the problem
