algorithm - Getting unique numbers efficiently? -

the problem in question check equation, example: a * b / c + d = x where - d unique numbers 1 - 4. now run through possibilities, skip when has duplicates, o(n^n), when should able solve o(n!) can't figure out how. is there algorithm this? based on wording (" a - d unique numbers 1 - 4 ") seems want algorithm generating possible permutations of set of numbers - in case set {1, 2, 3, 4} . given size of set, algorithm best implemented recursively: every element in set (from left right) generate permutations of remaining elements. note once last element, there's 1 possible order. this approach reduces problem of finding permutations of n items finding permutations of n-1 items. here's how on set {1, 2, 3} expect have 6 permutations: {1, 2, 3} 1 | {2, 3} 1 | 2 | {3} 1 | 2 | 3 1 | 3 | {2} 1 | 3 | 2 2 | {1, 3} 2 | 1 | {3} 2 | 1 | 3 2 | 3 | {1} 2 | 3 | 1 3 | {1, 2} 3 | 1 | {2} 3 | 1 | 2 3 | 2 | {1} 3 | 2 | 1 so algorithm gives following 6

c - Why is temporary storage needed in sorting array? -

the piece of code : if(a[i] > a[j]){ temp = a[i]; a[i] = a[j]; a[j] = temp; } why temp variable has used ? when try without temp : if(a[i] > a[j]){ a[i] = a[j]; } it wont work, before working when compare other variables if don't have temp variable temp = a[i]; a[i] = a[j]; a[j] = temp; then lose value in a[i] (previous assignment a[i] = a[j] . there way swap values without having using temporal value. solution here . in c this: int x = 10, y = 5; // code swap 'x' (1010) , 'y' (0101) x = x ^ y; // x becomes 15 (1111) y = x ^ y; // y becomes 10 (1010) x = x ^ y; // x becomes 5 (0101) using xor operator. code here , go link find entire explanation , possible drawbacks of using solution.

my c# form (visual studio 2008) has advanced mode more bells , whistles (larger form size) , normal mode (smaller form size). if user clicks on maximize button, i'd form toggle either advanced mode or normal mode, instead of maximizing form itself. is possible? i not believe there winforms event triggered maximize button. last time checked (years ago), can go down winapi level. protected override void wndproc( ref message m ) { base.wndproc(ref m); // call overwritten method first if( m.msg == 0x0112 ) // wm_syscommand { if (m.wparam == new intptr( 0xf030 ) ) //window being maximized { // things } } }

r - How are results of complete.cases() and data[is.na(data)] <- 0 different? -
