To Find the max & min elements in a array

here to find the minimum and maximum element in a array without using the minimum and maximum function, we are comparing all the elements to its previous element find the max and min value and then, the elements are returned back in a list with a use of simple for loop Intially, min -> arr[0] max -> arr[0] in a for loop -> i++ in a linear span compared to its element in list in loop arr[i] >< min or arr[i] >< max lets have a look into the code block, def minmax ( arr ): min = arr [ 0 ] max = arr [ 0 ] for i in range ( 1 , len ( arr )): if arr [ i ] < min : min = arr [ i ] elif arr [ i ] > max : max = arr [ i ] return [ min , max ] arr = [ 12 , 3 , 15 , 7 , 9 ] print ( minmax ( arr ))
