Sum of matrix element where each elements is integer division of row and column | Return sum of matrix element where each element is division of its corresponding row and column . ; For each column . ; count the number of elements of each column . Initialize to i - 1 because number of zeroes are i - 1. ; For multiply ; Driven Program
function findSum ( n ) { let ans = 0 , temp = 0 , num ; for ( let i = 1 ; i <= n && temp < n ; i ++ ) { temp = i - 1 ; num = 1 ; while ( temp < n ) { if ( temp + i <= n ) ans += ( i * num ) ; else ans += ( ( n - temp ) * num ) ; temp += i ; num ++ ; } } return ans ; } let N = 2 ; document . write ( findSum ( N ) ) ;
