Make all array elements equal to 0 by replacing minimum subsequences consisting of equal elements | Function to find minimum count of operations required to convert all array elements to zero br replacing subsequence of equal elements to 0 ; Store distinct elements present in the array ; Traverse the array ; If arr [ i ] is already present in the Set or arr [ i ] is equal to 0 ; Otherwise , increment ans by 1 and insert current element ; Given array ; Size of the given array
function minOpsToTurnArrToZero ( arr , N ) { var st = new Set ( ) ; for ( var i = 0 ; i < N ; i ++ ) { if ( st . has ( arr [ i ] ) arr [ i ] == 0 ) { continue ; } else { st . add ( arr [ i ] ) ; } } document . write ( st . size ) } var arr = [ 3 , 7 , 3 ] ; var N = arr . length ; minOpsToTurnArrToZero ( arr , N ) ;
