Therefore, the worst-case number of comparisons needed to select the second smallest is + ⌈ ⌉, the same number that would be obtained by holding a single-elimination tournament with a run-off tournament among the values that lost to the smallest value. However, the expected number of comparisons of a randomized selection algorithm can ...
The following pseudocode rearranges the elements between left and right, such that for some value k, where left ≤ k ≤ right, the kth element in the list will contain the (k − left + 1)th smallest value, with the ith element being less than or equal to the kth for all left ≤ i ≤ k and the jth element being larger or equal to for k ≤ j ≤ right:
6174 is a 7-smooth number, i.e. none of its prime factors are greater than 7. 6174 can be written as the sum of the first three powers of 18: 18 3 + 18 2 + 18 1 = 5832 + 324 + 18 = 6174, and coincidentally, 6 + 1 + 7 + 4 = 18. The sum of squares of the prime factors of 6174 is a square: 2 2 + 3 2 + 3 2 + 7 2 + 7 2 + 7 2 = 4 + 9 + 9 + 49 + 49 ...

In 2017, The Economist reported that the average decrease in the marathon record was 8 seconds per year for the previous 50 years and 9.4 seconds per year for the previous 20 years. If the record continued to reduce at either of these rates, then the 2-hour barrier would be crossed in 2040 or 2036, respectively.
Both the public and corporate workshops are half-day events, but over the years many people have been doing the workshop on their own, usually taking about three hours to get through the 10 questions. Watching them succeed so well on their own helped me realize this really can be a simple do-it-yourself process.
