Caselet Disscussion Take Home SIMCAT Refer to the data and answer the following questions Bungaland Intelligence Agency (BIA) has deputed a number of spies in the enemy territory to gather information on critical military installations of the enemy. The mission is being undertaken in complete secrecy. The spies are given numbers 1.2.3. Moreover, every spy is referred to by a unique code, which is known only to the c ntral high command of BIA in the capital city of Port Arthur. The following are the rules for assigning the codes to the spies Spy number 1 is given the code A and the spy number 2 is given the code B For spy numbered N (N > 2): 2 a. fN can be expressed as "N+N2. where N1 and Nz are two numbers (not necessarily unique) such that the spies bearing numbers N, and N2 both have one-letter codes (say and respectively), then the code of the spy numbered N is . .. For example, consider N 3. Because 3 1 + 2 and the spies numbered 1 and 2 both have one-letter codes (A and B respectively). the code of the spy numbered 3 is AB b. If N cannot be expressed as "N1 + N2. where N, and N2 are two numbers (not necessarily unique) such that the spies bearing numbers N, and Nz both have one-letter codes, the code of the spy numbered N is the next letter of the English alphabet. For example, code for the spy number 4 is BB and because 5 cannot be expressed as the sum of two numbers both having one-letter codes, the code for the spy numbered 5 is the next letter of the English alphabet i.e. C 3. The codes of all the spies (that have codes having two-letter codes) are in alphabetical order. For example, AB is a valid code but BA is not. 4. BIA deployed the maximum possible number of spies 'X' in the enemy territory such that all the spies numbered 1 to X had been given one- or two-letter codes only as per the above policy
