    Example 1 illustration
    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!!
    02 · Example 2
    BIN = 424242
N = 3
info = [["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!!
