The arrangement of keys on a keyboard affects not only typing but also can influence the efficiency of work on computers. Different layouts exist (like Dvorak, Colemak), designed to reduce finger movement and alternating hand use.

bottom_row = "zxcvbnm"def keyboard_walk_length(word): max_len = 1 cur_len = 1 for i in range(1, len(word)): if word[i] in bottom_row and word[i-1] in bottom_row: if abs(bottom_row.index(word[i]) - bottom_row.index(word[i-1])) == 1: cur_len += 1 max_len = max(max_len, cur_len) else: cur_len = 1 else: cur_len = 1 return max_len xcvbnm zxcvbnm

The QWERTY keyboard layout is the most commonly used keyboard layout in the world. It was designed in the 1870s for mechanical typewriters. The layout was engineered to solve a few problems: to slow down the typist's fingers to prevent keys from jamming together in mechanical typewriters, to have common letter combinations not be sequential (which would also cause jamming), and to facilitate telegraphy. The QWERTY keyboard layout is the most commonly
