WebMar 29, 2024 · You are swapping every row every time a new max is found. I've pushed this for loop out to swap only once per column. (I believe this is the loop hinted at by @DarryIG) And swapping only if the row is not in the right place already. The third nested forloop had row and column indices interchanged, so fixed it.

WebSep 21, 2024 · Swapping two values can be done in C++ simply with std::swap. return 0; at the end of the main program can be omitted. At some places your code does unnecessary work: If the diagonal element a[i][i] is zero then all subsequent rows with array[j][i] != 0 are swapped with the ith row. It suffices to swap one row with a non-zero leading element.
