Problem:
 Score : 100 points    Problem Statement You are given two integers a and b .
Determine if a+b=15 or a\times b=15 or neither holds.  Note that a+b=15 and a\times b=15 do not hold at the same time.      Constraints  1 \leq a,b \leq 15  All values in input are integers.         Input Input is given from Standard Input in the following format:  a  b       Output If a+b=15 , print + ;
if a\times b=15 , print * ;
if neither holds, print x .        Sample Input 1 4 11      Sample Output 1 +  4+11=15 .       Sample Input 2 3 5      Sample Output 2 *  3\times 5=15 .       Sample Input 3 1 1      Sample Output 3 x  1+1=2 and 1\times 1=1 , neither of which is 15 .

Solution (Python):

if a + b == 15:
    ans = "+"
elif a * b == 15:
    ans = "*"
else:
    ans = "x"
