Given an array of integers, find the second largest element in the array. If there is no second largest element, return -1.
Array: [12, 35, 1, 10, 34, 1]
Start with largest = -1 and second_largest = -1.
First element: 12 becomes the largest (largest = 12).
Next element: 35 is greater than 12, so 35 becomes the largest, and 12 becomes the second largest (largest = 35, second_largest = 12).
Next elements (1, 10, 34) are smaller than 35 but greater than 12, so second_largest becomes 34 after processing all elements.
Final result: The second largest value is 34.
You are given an array of characters, where each character represents the outcome of a game. The character 'A' indicates a win for Team A, and the character 'B' indicates a win for Team B. Your task is to count the number of wins for each team and determine which team has won the most games.
Array: ['B', 'A', 'B', 'B', 'A']
Initialize countA = 0 and countB = 0.
Traverse the array:
First element is 'B', so countB = 1.
Second element is 'A', so countA = 1.
Third element is 'B', so countB = 2.
Fourth element is 'B', so countB = 3.
Fifth element is 'A', so `countA = 2



You are given a string s. Your task is to find the first non-repeated character in the string and return it. If no such character exists, return -1.
Input: "level"
Count Frequencies:
'l' appears 2 times
'e' appears 2 times
'v' appears 1 time
First Non-Repeated Character:
The first character with a frequency of 1 is 'v'.
Output: 'v'
