String to integer ATOI (requires use of INT_MAX and INT_MIN): Implement the myAtoi(string s) function, which converts a string to a 32-bit signed integer (similar to C/C++'s atoi function). The algorithm for myAtoi(string s) is as follows: Read in and ignore any leading whitespace. Check if the next character (if not already at the end of the string) is '-' or '+'. Read this character in if it is either. This determines if the final result is negative or positive respectively. Assume the result is positive if neither is present. Read in next the characters until the next non-digit character or the end of the input is reached. The rest of the string is ignored. Convert these digits into an integer (i.e. "123" -> 123, "0032" -> 32). If no digits were read, then the integer is 0. Change the sign as necessary (from step 2). If the integer is out of the 32-bit signed integer range [-231, 231 - 1], then clamp the integer so that it remains in the range. Specifically, integers less…

✓ Allowed languages C Problem Statement Given an integer N followed by N integers A₁ up to AN, output the sum of the N integers. Input Input starts with a number N and is followed by N integers. Output Output is a single line containing the sum of the N integers. Do not output any newline characters. Limits 1 < N < 20 -1000 ≤ A ≤ 1000 Notes Problems will have test cases that are not listed in their specification. Your solution must produce the right output for these hidden test cases.
