Today's work force is in question brush wear. Here attached a topic.
Two numbers and
given an integer array nums and a target value target, and ask you to identify the target value of the two integers in the array, and return to their array subscript.
You can assume that each input corresponds to only one answer. However, you can not re-use the same array element.
Example:
Given nums = [2, 7, 11, 15], target = 9
Because nums [0] + nums [1 ] = 2 + 7 = 9
is returned [0, 1]
class Solution:
def twoSum(self, nums: List[int], target: int) -> List[int]:
for i in range(len(nums)):
for j in range(i+1,len(nums)):
if nums[i]+nums[j] == target:
return [i,j]
