Given integers **x** and **y** which denotes the average temperature of the week except for days **Day1** and **Day2** respectively, and the sum of the temperature of **Day1** and **Day2** as **S**, the task is to find the temperature of the days **Day1** and **Day2**.**Examples:**

Input:x = 15, y = 10, S = 50Output:Day1 = 10, Day2 = 40Explanation:

The average of week excluding Day1 is 15, the average of week excluding Day2 is 10 and the sum of temperature of Day1 and Day2 is 50. Individual temperature of the two days are 10 and 40 respecticvely.Input:x = 5, y = 10, s = 40Output:Day1 = 35, Day2 = 5Explanation:

The average of week excluding Day1 is 5, the average of week excluding Day2 is 10 and the sum of temperature of Day1 and Day2 is 40. Individual temperature of the two days are 35 and 5 respecticvely.

**Approach:** We know that** Average = sum of all observation / total number of observation.** Hence, the sum of observation = Average * number of observation i.e., **S = A * n**

So after excluding Day1 or Day2 we are left with only 6 days

so N = 6 and the equations are:

and

on subtracting the above two equations we get,

(Equation 1)

and it is given in the problem statement that

(Equation 2)

Solving the above two equations, the value of Day1 and Day2 is given by:

[Tex]Day1 = S – Day2 [/Tex]

Below is the implementation of above approach:
