Hi, just looking for help on this work below. Design a deterministic Finite Automaton (FA) to recognise arithmetic expressions The following are some examples of arithmetic expression: 1. Any number string with or without signs - e.g. 3, -1, +10, 3.14, -0.70 and 099. 2. Number strings mixed with arithmetic operators - e.g. 3+5, -1+2*3, 7/10-0.7, and -1.4-+8.2. Any help or ideas to solve would be appreciated.
Please Use Only C++ Language. C++ Language answer will get the upvote surely. The chef has N marks. Each marker has a cap. For each valid i, the ith tag has color ai And initially, for each valid i, the cap colour on the ith mark is also ai. The chef wants to rearrange the caps so that no tag has the same color as the cap. (Obviously, each brand must have exactly one cap.) Can he, do it? If he can, find one such way to rearrange the caps. If there are multiple solutions, you can find any. Input 2 9 111222333 2 11 Output Yes 22 23 33 111 No
