+Implement the myAtoi(string s) function, which converts a string to a 32-bit signed integer.
+
+The algorithm for myAtoi(string s) is as follows:
+
+Whitespace: Ignore any leading whitespace (" ").
+Signedness: Determine the sign by checking if the next character is '-' or '+', assuming positivity if neither present.
+Conversion: Read the integer by skipping leading zeros until a non-digit character is encountered or the end of the string is reached. If no digits were read, then the result is 0.
+Rounding: If the integer is out of the 32-bit signed integer range [-231, 231 - 1], then round the integer to remain in the range. Specifically, integers less than -231 should be rounded to -231, and integers greater than 231 - 1 should be rounded to 231 - 1.
+Return the integer as the final result.
+Example :
+
+Input: s = " -042"
+
+Output: -42
+
+Explanation:
+
+Step 1: "   -042" (leading whitespace is read and ignored)
+            ^
+Step 2: "   -042" ('-' is read, so the result should be negative)
+             ^
+Step 3: "   -042" ("042" is read in, leading zeros ignored in the result)
