    Permutations of 2d arrays

    How do I write a code in C to check if two matrices with dimensions and elements entered by a user (max dimension [100] [100]) are permutations of each other without any special functions or libraries?

    Well what counts as a permutation?

    Is this anything to do with it?

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
