Correct answer: A
To find the positions of keys 177 and 197 in a hash table of size 57 using the division method h(k) = k mod m, compute the hash value for each key.
For key 177:
h(177) = 177 mod 57
57 × 3 = 171, and 177 - 171 = 6.
So, h(177) = 6.
For key 197:
h(197) = 197 mod 57
57 × 3 = 171, and 197 - 171 = 26.
So, h(197) = 26.
Therefore, the keys 177 and 197 are stored at positions 6 and 26, respectively.
