Given a list of N + 1 numbers, N mixed up with them, find the maximum number between this N numbers.

EXPLANATION

Let A be the original list of size N. The number N was added in this list. Let the updated list be B. We can find the list A from the list B by finding any occurrence of the number N and deleting it. Finding maximum in a list can be done by iterating over its elements in linear time.

Parsing the input into a list of integers
For reading a line from standard input, you can use

getline(cin, s)

, it will read a line and save it in string s.

You can parse the input string into integers as follows. Use [string stream][4], read a line by

getline

and put it into some stringstream, then read ints one by one until it has some. You can check if it has some using

ss >> a

, it will return false if nothing is remained in stringstream (see my code for better understanding).
**IMPLEMENTATION** -
Setter's code - [here][1] (using getline and stringstream).
Tester's code - [here][2] (using getline and parsing the input manually).
Second tester's code - [here][3] (using getline and parsing the input manually).

I submitted the first problem yesterday and got WA. I got demotivated and left because the first problem was the easiest. Today, I came back online and saw (with some pleasant surprise and happiness) that it did get accepted ! Can someone explain what happened ?

What is wrong with my solution? I have tested all possible test cases.This is my submission for LOSTMAX from LTIME50. Further clarifications on where I went wrong is appreciated. Thank You.

@sprea27
If c[0]=c.size()-1 and it is the greatest element then your code give that as output which is wrong.
Input
3 1 2 1
your code output:3
correct output: 2
So put c=0 or any negative number and run loop from 0.You will get AC.

Second TC has array numbers >9, i.e. 2 digit numbers. If you are taking entire line as input (as string), then make sure you are correctly assigning values to array. I.e. storing 19 in array instead of 1 and 9 in 2 adjacent indices.

Maybe languages like python can help a Lot in these cases.
We can take input without reading the number of inputs in single line in python
while input().split() and using map().
Makes code really simple.
