Question: How many rounds are in the tournament where Sherron Collins earned three championships?
Context: The 1960 Campionatio Italiano was the 3rd season of the Campionato Italiano.  Renato Pirocchi won this championship.  Many rounds were run in conjunction 1960 Campionatio A.N.P.E.C./Auto Italiana d’Europa (World Car Trophy Italian ANPEC), which saw Colin Davis win the title. Chris Collins earned United States Intercollegiate Lacrosse Association honorable mention All American honors in 2005 after leading the nationally ranked Blue Hens to an 11-6 record, the Colonial Athletic Association regular season title, and a berth in the NCAA Tournament. The exhaustive ballot is a voting system used to elect a single winner.  Under the exhaustive ballot the elector simply casts a single vote for his or her favorite candidate.  However, if no candidate is supported by an overall majority of votes then the candidate with the fewest votes is eliminated and a further round of voting occurs.  This process is repeated for as many rounds as necessary until one candidate has a majority. On April 13, 2009 key players Sherron Collins and Cole Aldrich announced that they would forgo the NBA draft and return for the 2009–10 season.  The Jayhawks will return all players who saw significant minutes on last years Sweet 16 team.  In early polls for the season, The Jayhawks were almost the consensus #1 ranked team for the 09–10 season, the only other team that was #1 in any other pre-season polls, was Michigan State, which defeated KU in the Sweet 16 of the 2009 NCAA tournament. The contingent vote is an electoral system used to elect a single winner, in which the voter ranks the candidates in order of preference.  In an election, if no candidate receives an absolute majority of first preference votes, then all but the two leading candidates are eliminated and there is a second count.  In the second count, the votes of those who supported eliminated candidates are distributed among the two remaining candidates, so that one candidate achieves an absolute majority.  The contingent vote is similar to the alternative vote but differs from it in that the alternative vote typically allows for many rounds of counting, whereas under the contingent vote there are never more than two.  In the United States both the contingent vote and the alternative vote are often referred to as variants of instant-runoff voting.  The contingent vote can also be considered a compressed form of the two round system (runoff system), in which both 'rounds' occur without the need for voters to go to the polls twice. The 2010 Phillips 66 Big 12 Men's Basketball Championship was the 2010 edition of the Big 12 Conference's championship tournament held at Sprint Center in Kansas City, Missouri from March 10 until March 13, 2010.  It was won by top-seeded Kansas.  The all-tournament team consisted of Kansas' Sherron Collins and Cole Aldrich, Kansas State's Jacob Pullen and Denis Clemente, and Texas A&M's Donald Sloan. The Big 12 Men's Basketball Tournament (known since its inception in 1997 under sponsorship agreements as the Phillips 66 Big 12 Men's Basketball Tournament) is the championship men's basketball tournament in the Big 12 Conference.  It is a single-elimination tournament of four rounds, with the top four seeds getting byes in the first round.  Starting in 2012, the top six seeds will get byes in the first round.  Seeding is based on regular season records. Sherron Marlon Collins (born March 18, 1987) is an American professional basketball player who last played for the Windsor Express of the National Basketball League of Canada (NBL).  He formerly played for the Charlotte Bobcats of the National Basketball Association (NBA).  He has also played for the Texas Legends and Maine Red Claws of the NBA D-League and Hacettepe Üniversitesi in the Turkish Basketball League.  As an All-American member of the Kansas Jayhawks men's basketball team, he earned a national championship in the 2008 NCAA Men's Division I Basketball Tournament, three Big 12 Men's Basketball Tournament championships, and four consecutive Big 12 Conference regular season championships.  He was regarded as one of the leaders of the team and was its captain during his senior year. Rocket are an alternative rock, post grunge, rocknroll group formed in Los Angeles, California.  They are known for their up-beat sound and high energy performances.  Members are Janelle Barreto (vocals), Eric Wibbelsmann (guitar), Steven Kilcullen (rhythm guitar), Jordan Lawson (bass), and Paul DePatie (drums).  Wibbelsmann and DePatie were previously in a band called The Pills and had lost their lead singer.  They placed an ad on Craigslist listing influence bands like Soundgarden, Pearl Jam, Stone Temple Pilots and Jane’s Addiction, which attracted Barreto who then responded.  After many rounds of meeting and auditioning singers from all walks of life, they offered Barreto the job.  The band began performing in and around the LA area until around July of 2017 when their original bass player Bill Luna left the group due to creative differences.  The three other members began auditioning again, only this time they were seeing new bassists and also hoping for another guitarist to complete the five piece band they envisioned.  After a month's worth of searching and vibing out many other musicians, the band hired Lawson as their new bassist and Kilcullen to play rhythm guitar.  The newly formed group are currently completing an EP "Get Huge" which is set for release in late 2017, performing bigger venues and gaining much more popularity with their new lineup and material. In computational complexity theory, the class QIP, which stands for Quantum Interactive Polynomial time, is the quantum computing analogue of the classical complexity class IP, which is the set of problems solvable by an interactive proof system with a polynomial-time verifier and one computationally unbounded prover.  Informally, IP is the set of languages for which a computationally unbounded prover can convince a polynomial-time verifier to accept when the input is in the language (with high probability) and cannot convince the verifier to accept when the input is not in the language (again, with high probability).  In other words, the prover and verifier may interact for polynomially many rounds, and if the input is in the language the verifier should accept with probability greater than 2/3, and if the input is not in the language, the verifier should be reject with probability greater than 2/3.  In IP, the verifier is like a BPP machine.  In QIP, the communication between the prover and verifier is quantum, and the verifier can perform quantum computation.  In this case the verifier is like a BQP machine.
