+# [Solve Me First](https://www.hackerrank.com/challenges/solve-me-first)
+
+Difficulty: #easy
+Category: #warmup
+
+Complete the function solveMeFirst to compute the sum of two integers.
+
+## Example
+
+$ a = 7 $ \
+$ b = 3 $
+
+Return 10.
+
+## Function Description
+
+Complete the solveMeFirst function in the editor below.
+solveMeFirst has the following parameters:
+
+- int a: the first value
+- int b: the second value
+
+## Constraints
+
+$ 1 \leq a, b \leq 1000 $
+
+## Sample Input
+
+```text
+a = 2
+b = 3
