Bobo found this really big number - it has 1000 digits. (It's one number but written on several lines just so it can fit on the page). 731671765313306249192251196744265747423553491949349698352031277450632623957831801698480186947885184385861560789112949495459501737958331952853208805511125406987471585238630507156932909632952274430435576689664895044524452316173185640309871112172238311362229893423380308135336276614282806444486645238749303589072962904915604407723907138105158593079608667017242712189399879790879227492190169972089809377665727333001053367881220235421809751254540594752243525849077116705560136048395864467063244157221553975369781797784617406495514929086256932197846862248283972241375657056057490261407972968652414535100474821663704844031998900089952434506585412275886668116427171479924442928230863465674813919123162824586178664583591245665294765456828489128831426076900422421902267105562632111110937054421750694165896040807198403850962455444362981230987879927244284909189845801561660979191338754992005240636899125607176060588611646710940507754100225698315520005593572972571636269561892670428252483600823257530420752963450 Working from the beginning to the end of the big number, Bobo wants to find the five-digit group that adds up to the biggest sum. There's one rule for Bobo to remember, and that is that each 5-digit group is built upon every single digit in the big number, except for the final four digits. What this means is that the first two five-digit groups will be 73167 and 31671 and so on. The last five-digit group will be 63450 . Using the first five-digit number, a sum is to be calculated in the following way: sum =(7+3+1+6+7). Bobo is stumped. Please list steps to help Bobo find the 5-digit group with the biggest sum. Bobo doesn't want you to find the answer, he'll do that. He just wants you to tell him the steps to go about finding the
