<!--l. 30--><p class="indent" > Compute the degree <span

class="cmmi-8">i</span></sub>(<span
class="cmmi-10x-x-109">t</span>) of node <span
class="cmmi-10x-x-109">i </span>in a growing network as a function of
time. The file <span
class="cmti-10x-x-109">layer </span>contains the edge list of the final network. Each line of the
file is in the format:

class="cmti-10x-x-109">_ID dest</span><span

<!--l. 30--><p class="indent" > where <span

class="cmti-10x-x-109">dest</span><span

edge.
<!--l. 30--><p class="indent" > The file <span

class="cmti-10x-x-109">_i node</span><span

<!--l. 30--><p class="indent" > where <span
class="cmti-10x-x-109">time</span><span
class="cmti-10x-x-109">_i </span>is the time at which <span
class="cmti-10x-x-109">node</span><span
class="cmti-10x-x-109">_i </span>arrived in the graph. Notice that
<span
class="cmti-10x-x-109">time</span><span
class="cmti-10x-x-109">_i </span>must be an integer in the range [0, N-1], where N is the total number of
nodes in the final graph.
<!--l. 30--><p class="indent" > The third parameter <span
class="cmti-10x-x-109">node</span><span
class="cmti-10x-x-109">_id </span>is the ID of the node whose degree over time
will be printed on output. If more than one <span

class="cmti-10x-x-109">_id </span>is provided, the degrees over
time of all the corresponding nodes are printed on output.
