Cost required to make all array elements equal to 1 | Function to calculate the cost required to make all array elements equal to 1 ; Stores the total cost ; Traverse the array arr [ ] ; If current element is 0 ; Convert 0 to 1 ; Add the cost ; Return the total cost ; Driver Code
function findCost ( A , N ) { var totalCost = 0 ; var i ; for ( i = 0 ; i < N ; i ++ ) { if ( A [ i ] == 0 ) { A [ i ] = 1 ; totalCost += i ; } } return totalCost ; } var arr = [ 1 , 0 , 1 , 0 , 1 , 0 ] var N = arr . length document . write ( findCost ( arr , N ) ) ;
