Question

so Tools Window Help s CSE30.s16 HW1.pdf (page 3 of 5 Search Problem 3. [24 pts) Draw the recursion trace for the execution of function sis empty and U (a, b, c, dh. List all the Prints(3,S,U, where printouts of s. Algorithm Prints (k, S, Input: An integer k, sequence s, and set v output: An enumeration of all k-length extensions to s using elements in U without repetitions for each e in U do Remove e from U te is now being used Add e to the end of S if k 1 then Print else Prints (k-1, S, Add e back to U (e is now unusedk Remove e from the end of S

Explanation / Answer

Please find the recursion trace below :

[a, b, c]
[a, c, d]
[d, b, c]
[d, c, a]
[c, b, a]
[c, a, d]

For your execution, find the implemention in java below :
