Count Binary Strings

#1

I am getting correct answer for the given test cases…is the logic wrong or is there some bug in the code i am passing only first test case?

@aryamaan1011 your logic is incorrect!
you can add 0 to any previous string
so dp[0][i] = dp[0][i-1] + dp[1][i-1]
but you can add 1 only to previous strings ending with 0
so dp[1][i] = dp[0][i-1]
