Automorphic Number | Function to check Automorphic number ; Store the square ; Start Comparing digits ; Return false , if any digit of N doesn ' t ▁ ▁ match ▁ with ▁ its ▁ square ' s digits from last ; Reduce N and square ; Driver code
function isAutomorphic ( N ) { let sq = N * N ; while ( N > 0 ) { if ( N % 10 != sq % 10 ) return - 1 ; N /= 10 ; sq /= 10 ; } return 1 ; } let N = 5 ; let geeks = isAutomorphic ( N ) ? " " : " " ; document . write ( geeks ) ;
