def twoSumnums target Given an array of integers nums and an integer target return indices of the two numbers such that they add up to target hash_table = for i num in enumeratenu

The function twoSum takes in an array of integers nums and an integer target. It returns the indices of two numbers in the array that add up to the target.

The function uses a hash table to store the complement of each number encountered. The complement is calculated as the difference between the target and the current number. If the complement is already in the hash table, it means that the current number and its complement add up to the target. In this case, the function returns the indices of the current number and its complement. If the complement is not in the hash table, the current number is added to the hash table with its index as the value.

The function is tested with three test cases:

1. twoSum([2, 7, 11, 15], 9): The array contains numbers 2, 7, 11, and 15. The target is 9. The function should return the indices of numbers 2 and 7, which are 0 and 1, respectively.

2. twoSum([3, 2, 4], 6): The array contains numbers 3, 2, and 4. The target is 6. The function should return the indices of numbers 2 and 4, which are 1 and 2, respectively.

3. twoSum([3, 3], 6): The array contains numbers 3 and 3. The target is 6. The function should return the indices of the two 3s, which are 0 and 1, respectively
