You are given N golden balls,you have to find the maximum height of triangle it can form with that balls.

A traingle with height X will have X balls in the bottom most level and 1 ball in the top most level

each upper level will have exactly one ball less than its bottom level.

//here’s my code

#include<stdio.h>

#include<math.h>

int main()

{

int t;

long long int n;

float h;

scanf(“%d”,&t);

while(t–)

{

scanf(“%lld”,&n);

h=(-1+sqrt(1+8*n)/2;

printf(“%d\n”,(int)h);

}

return 0;

}
