For each of the following code snippets, - (10 points) Count (or calculate) how many times the line "code with 0(1)n is executed. - (5 points) From your count, find the time complexity of the code snippet. Show your work for full credit. 1. (15 points) for i in range (N) : for j in range (N) : for k in range (M) : code with O(1) 2. (15 points) control = N; while control I=0: code with 0(1) control //=2 3. (15 points) for counter in range (N) : control =1 while control
