Function

cardRangeObfuscation4(BIN: int, N: int, info: String[][]) → String[][]

Examples

Example 1

BIN = 424242N = 2info = [["0000000000","5999999999","VISA"],["6000000000","9999999999","VISA"]]return = [["4242420000000000", "4242429999999999", "VISA"]]

Example 1: the two adjacent VISA intervals were merged Note - I double checked the input & output numbers while uploading, but since there are so many digits, I might count them wrong. If you notice anything wrong, pls feel free to lmk. I am more than happy to modify accordingly. Many thanks in advance! You da best!!

Example 2

BIN = 424242N = 3info = [["1000000000","3999999999","VISA"],["5000000000","6999999999","VISA"],["8000000000","9999999999","MASTERCARD"]]return = [["4242420000000000", "4242427999999999", "VISA"],["4242428000000000", "4242429999999999", "MASTERCARD"]]

Example 2: the VISA intervals were extended to fill the gaps, then merged. Note - I double checked the input & output numbers while uploading, but since there are so many digits, I might count them wrong. If you notice anything wrong, pls feel free to lmk. I am more than happy to modify accordingly. Many thanks in advance! You da best!!
