60번의 시도로 계산하랍니다. 그냥 간단한 코딩 MISC문제..

코드는 더러워도 이해해주세요.ㅋㅋ

nopsled@smleeo3o:~/Desktop (=｀ω´=)$ python test.py Lovely Calculation! This problem includes 60 rounds. Specific Info. 1.Each round has 3 sec. time limit. And all of the answers will be INTEGER ONLY! 2.From round 1 to round 20, there will be less than 5 numbers that you should calculate. The operators will be +,-,*,%. 3.From round 21 to round 40, there will be more than 5 numbers that you should calculate. Also, the equation can have parenthesis. The operators will basically same as round 1 to 20. 4.From round 41 to round 60, there will be more than 10 numbers that you should calculate. Also, the equation can have parenthesis and &,|,^ operator. It follows the standard C language's operator precedence. 5.The operators are little bit different. + -> -, - -> +, * -> /, / -> *, & -> ^, | -> &, ^ -> | What is your name? : Have Fun!(Press Any Key) Round 1 : 7+5*7%1 Answer :  7 7-5/7%1 Round 2 : 2/1+4-2 Answer :  0 2*1-4+2 Round 3 : 4+5%3 Answer :  2 4-5%3 Round 4 : 1%6-8+3 Answer :  6 1%6+8-3 Round 5 : 4+6 Answer :  -2 4-6 Round 6 : 2%6 Answer :  2 2%6 Round 7 : 8+7 Answer :  1 8-7 Round 8 : 9+8 Answer :  1 9-8 Round 9 : 7+9 Answer :  -2 7-9 Round 10 : 5-8 Answer :  13 5+8 Round 11 : 4%1+5+7 Answer :  -12 4%1-5-7 Round 12 : 9/1 Answer :  9 9*1 Round 13 : 2/4+1 Answer :  7 2*4-1 Round 14 : 9%1*4%4 Answer :  0 9%1/4%4 Round 15 : 5-4+4%2 Answer :  9 5+4-4%2 Round 16 : 8%5*2+3 Answer :  -2 8%5/2-3 Round 17 : 8-5 Answer :  13 8+5 Round 18 : 2+1 Answer :  1 2-1 Round 19 : 6*3 Answer :  2 6/3 Round 20 : 1+2+8+7 Answer :  -16 1-2-8-7 Round 21 : (4*1-7+5)-1*1*2 Answer :  6 (4/1+7-5)+1/1/2 Round 22 : 1*1+4+9*2 Answer :  -7 1/1-4-9/2 Round 23 : 7-9/5+1/8+1*4-1%3 Answer :  45 7+9*5-1*8-1/4+1%3 Round 24 : 1*7/1+2%4 Answer :  -2 1/7*1-2%4 Round 25 : 1*1*4*2+7*3%1*7 Answer :  0 1/1/4/2-7/3%1/7 Round 26 : 7*7*1-7-3 Answer :  11 7/7/1+7+3 Round 27 : 5+8*7-4/8-4-9+1 Answer :  48 5-8/7+4*8+4+9-1 Round 28 : 1+1/1+1*4 Answer :  0 1-1*1-1/4 Round 29 : 8*3%1+8+3-9+1+7 Answer :  -10 8/3%1-8-3+9-1-7 Round 30 : 6-1/1/1+4 Answer :  3 6+1*1*1-4 Round 31 : 3+4+5-4*1%7+2+7 Answer :  -11 3-4-5+4/1%7-2-7 Round 32 : 3+4/1+8-3/7/4/2*8 Answer :  12 3-4*1-8+3*7*4*2/8 Round 33 : 7*4*6*7+1+9 Answer :  -10 7/4/6/7-1-9 Round 34 : 1+7%1%8%6+9+1 Answer :  -9 1-7%1%8%6-9-1 Round 35 : 4-6+5%4-7*1 Answer :  16 4+6-5%4+7/1 Round 36 : 1-7%1/9-4*8/1 Answer :  1 1+7%1*9+4/8*1 Round 37 : 3%1+5%1+6*1+7*1+5 Answer :  -18 3%1-5%1-6/1-7/1-5 Round 38 : 3-8/4+3+9 Answer :  23 3+8*4-3-9 Round 39 : 1/9-6+7/1-1+2-2/8 Answer :  23 1*9+6-7*1+1-2+2*8 Round 40 : 6+3%8+1-6 Answer :  8 6-3%8-1+6 Round 41 : 8+7|(7-1)+4|7^5*4 Answer :  1 8-7&(7+1)-4&7|5/4 Round 42 : 3|8%2-7%4 Answer :  3 3&8%2+7%4 Round 43 : 1^3+7-4%6+3+7+3 Answer :  -13 1|3-7+4%6-3-7-3 Round 44 : 1%9+1-5+3 Answer :  2 1%9-1+5-3 Round 45 : 7+5+4-5|9/1+9^4 Answer :  4 7-5-4+5&9*1-9|4 Round 46 : 3+8+1+7|6+1%1%2%8 Answer :  2 3-8-1-7&6-1%1%2%8 Round 47 : 1&4+3%2*1+1 Answer :  3 1^4-3%2/1-1 Round 48 : 1+6+1^6^8&1%1+1+9 Answer :  -2 1-6-1|6|8^1%1-1-9 Round 49 : 3/5+9*1+4/3 Answer :  -6 3*5-9/1-4*3 Round 50 : 4%1+7^7+8^4%4 Answer :  -1 4%1-7|7-8|4%4 Round 51 : 5-9%1+7-6+9 Answer :  -5 5+9%1-7+6-9 Round 52 : 3+1+2*8^4*9*4%1%7 Answer :  2 3-1-2/8|4/9/4%1%7 Round 53 : 4*7|1|3%3+5-4+4*1 Answer :  0 4/7&1&3%3-5+4-4/1 Round 54 : 1+7*7|6+9 Answer :  0 1-7/7&6-9 Round 55 : 3%1^4/7/2+1%1%1 Answer :  56 3%1|4*7*2-1%1%1 Round 56 : 8+5^6/8/4 Answer :  195 8-5|6*8*4 Round 57 : 4^1*2|8%9*1+3+9 Answer :  4 4|1/2&8%9/1-3-9 Round 58 : 1+4*1|7^1 Answer :  5 1-4/1&7|1 Round 59 : 7+1^3%1%6^2^3%5 Answer :  7 7-1|3%1%6|2|3%5 Round 60 : 2-9^4+1*1 Answer :  11 2+9|4-1/1 Congrats!
