C++ Problem!! Sort A List Of Integers Given a file of 100,000 unsorted integers, write a program that first prompt user to enter file name and reads those integers into an array and sorts the integers in the array. The program should then prompt the user for an index, and then display the integer at that index. For example, if the array contains ten integers and the contents are 79 4 42 51 12 22 33 17 91 10 after sorting, the integer at index 6 is 42 Download the "List of 100,000 Unsorted Integers" from below link and sort that list, then enter the value at index 10000 (ten thousand) for a screenshot. https://1drv.ms/t/s!AuFS4mkcuYyBjHZ_SIudb93bq2uy?e=CsyvZj

4. Choose any 1 cipher methods of your choice and explain its working with example
Each of the following is a true/false statement about a tweakable block cipher (TBC). Place a checkmark next to each true statement. In the questions mentioning E', let E' be a random instance of a TBC and E'(T,X) be the result of using E' with tweak T and input X. Group of answer choices: (1)For TBC security both the current key and tweak in use must be kept secret from adversaries. (2)Each time a new tweak is given to a TBC, the TBC behaves like a new random permutation. (3)When a TBC is used once per tweak its outputs may be considered (4)A TBC is a prominent part of the design of OCB. (5)If X1 ≠ X2, then always E'(T,X1) ≠ E'(T,X2) (6)If T1 ≠ T2, then always E'(T1,X) ≠ E'(T2,X)
