also known as cryptarithmetic is a type of puzzle where you have to assign digits to alphabets such that no two alphabets get the same digits.only numbers from 0 -9 can be assigned.ex
send
+more=
money

values after solving are:
O = 0, M = 1, Y = 2, E = 5, N = 6, D = 7, R = 8, and S = 9

int a=4,b=5;
int x=++a*++a*++a;
int y=++a*++b*++b;
printf("%d,%d",x,y);

Please explain each step??

         unsigned int b=2; int a=-2;

          if(a>b)
                 printf("a>b");
          else
              printf("b>a");

OUTPUT: a>b

         int b=2; int a=-2;

Hello guys, I have this assignment to create a function that returns the level of a node. I insert the letters of the word "procedure" in that order and the function should find and return the level of every character. This is what I have done so far but I don't get the result and I don't understand why. The function that I create is BSTLevel.
