First Round Manager Screen

This round of communication was relaxed and pleasant, mainly focusing on regular behavioral questions, and both parties communicated smoothly.

Second round OA

The number of topics is high and requires some effort and time.

Salesforce OA - String Subsequences

Title:Given two strings, count the number of times the first string appears as a subsequence in the second string. Removal of any character is allowed, but the order cannot be changed.

s1 = "ABC"
s2 = "ABCBABC"

In s2, "ABC" occurs 5 times as a subsequence, and the corresponding position combinations are (1,2,3), (1,2,7), (1,4,7), (1,6,7) and (5,6,7). The answer is 5.

function signature

Please complete the function getSubsequenceCount(s1, s2) Returns the number of occurrences of the subsequence.

sample code (computing)

def getSubsequenceCount(s1, s2).
    n1, n2 = len(s1), len(s2)
    dp = [[0]*(n2+1) for _ in range(n1+1)]
    for j in range(n2+1).
        dp[0][j] = 1
    for i in range(1, n1+1): for j in range(1, n1+1): dp[0][j] = 1
        dp[0][j] = 1 for i in range(1, n1+1): for j in range(1, n2+1).
            if s1[i-1] == s2[j-1].
                dp[i][j] = dp[i-1][j-1] + dp[i][j-1]
            else.
                dp[i][j] = dp[i][j-1]
    return dp[n1][n2]
