please write in c++.

Consider combinatorial puzzles,for example, one such puzzle is POT + PAN = BIB. In these puzzles, you must assign each letter a distinct digit, such that if we substitute the digits in place of the letters, the resulting mathematical equation is true. In our continuing example, if we set P=2, O=3, T=1, A=7, N=4, B=5, and I=0, we get 231 + 274 = 505..

in the file proj0.cpp, you will find an incomplete implementation for:

bool verifySolution(std::string s1, std::string s2, std::string s3, const std::map & mapping)

Your assignment is to finish implementing this. To find out what the proposed mapping has for s1[0] (the first character in std::string s1), you can use the member function at of the map class: that is, mapping.at(s[0]). You are not required to check that the digits assigned are distinct, merely that it satisfies the equation.

code:

#include

#include

bool verifySolution(std::string s1, std::string s2, std::string s3, const std::map & mapping)

{

return false; // FYI, this stub is not a correct solution.

}
