text: Minimize count of increments of each element of subarrays required to make Array non | Function to find the minimum number of operations required to make the array non - increasing ; Stores the count of required operations ; If arr [ i ] > arr [ i + 1 ] , no increments required . Otherwise , add their difference to the answer ; Return the result res ; Driver Code
code: function getMinOps ( arr ) { var res = 0 ; for ( i = 0 ; i < arr . length - 1 ; i ++ ) { res += Math . max ( arr [ i + 1 ] - arr [ i ] , 0 ) ; } return res ; } var arr = [ 1 , 3 , 4 , 1 , 2 ] ; document . write ( getMinOps ( arr ) ) ;
