HackerEarth Soft Sort problem solution YASH PAL, 31 July 202413 February 2026 In this HackerEarth Soft Soft problem solution Let us define an easy Sorting Algorithm called SoftSort. SoftSort Sorting algorithm involves the use of IF and ELSE decision statements only. For example : To sort two numbers a and b. SoftSort Algorithm’s Code is given below. void print(int a,int b){ printf( “%d %dn”,a,b);}void sort( int a, int b){ if( b < a ) print( b, a ); else print( a, b );}To sort three numbers a , b and c . Source Code is given below. void print( int a, int b, int c ) { printf( “%d %d %dn”, a, b, c );}void sort( int a, int b, int c ) { if( a < b ) if( a < c ) if( b < c ) print( a, b, c ); else print( a, c, b ); else print( c, a, b ); else if( b < c ) if( a < c ) print( b, a, c ); else print( b, c, a ); else print( c, b, a ); }ANI is fascinated with the SoftSort Algorithm and decided to ask an interesting question to KUKU. What could be the length of source code to sort n numbers using SoftSort Algorithm?
