Implement the following function: def permutations (lst) the function is given a list 1st of integers, and returns a list containing all the different permutations of the elements in 1st. each such permutation should be represented as a list. for example, if lst= [1, 2, 3j, the call permutations (1st) could return , 2, 3], [2, 1, 3, [1, 3, 2], [3, 2, 1, [3, 1, 2], [2, 3, 111 implementation requirements 1. your implementation should be non-recursive. 2. your implementation is allowed to use a stack, a queue, and θ (1) additional space hint: use the stack to store the elements yet to be used to generate the permutations, and use the queue to store the (partial)collection of permutations generated so far.

Creating "smart interfaces" in all sectors of industry, government, and the public arena is one of the fastest growing hct areas. these interfaces model, interpret, and analyze such human characteristics as speech, gesture, and vision. the field of biometrics, in which humans authenticate themselves to machines, is an area of considerable interest to hct practitioners. fingerprint scans are one of the most frequently used biometric options, and this article, biometric student identification: practical solutions for accountability & security in schools, makes a case for the implementation of fingerprint scans in schools. critique the article, and answer the following questions: according to the author, what are the main benefits of adopting fingerprint scans in schools for student identification? according to the author, what are the main drawbacks of adopting fingerprint scans in schools for student identification? do you agree with the author's assessment of the pl
