- Elements fit in memory standard spaces.

Accepted Answer

```
def lengthOfLongestSubstring(s):
    char_map = {}
    left = 0
    max_len = 0
    for right, char in enumerate(s):
        if char in char_map and char_map[char] >= left:
            left = char_map[char] + 1
        char_map[char] = right
        max_len = max(max_len, right - left + 1)
    return max_len
